Probability unit 9

Many events can't be predicted with total certainty. The best we can say is how likely they are to happen, using the idea of probability. When a single die is thrown, there are six possible outcomes: 1, 2, 3, 4, 5, 6. But when we actually try it we might get 48 heads, or 55 heads There are 4 Kings, so that is 4 different sample points.

The Event Alex is looking for is a "double", where both dice have the same number. It is made up of these 6 Sample Points :. After ExperimentsAlex has 19 "double" Events Hide Ads About Ads.

Probability How likely something is to happen. Example: there are 5 marbles in a bag: 4 are blue, and 1 is red. What is the probability that a blue marble gets picked? Example: toss a coin times, how many Heads will come up? Experiment: a repeatable procedure with a set of possible results. Example: Throwing dice We can throw the dice again and again, so it is repeatable.

Example: Getting a "6". Example: Deck of Cards the 5 of Clubs is a sample point the King of Hearts is a sample point "King" is not a sample point. Example: Throwing dice There are 6 different sample points in the sample space. Example Events: An event can be just one outcome: Getting a Tail when tossing a coin Rolling a "5" An event can include more than one outcome: Choosing a "King" from a deck of cards any of the 4 Kings Rolling an "even number" 2, 4 or 6.

Example: Alex wants to see how many times a "double" comes up when throwing 2 dice.The questions that are provided in this exercise discuss various methods and rules on how to find out the probability of a particular event.

This topic lends itself to a lot of hands-on demonstrations and activities, which can be really fun. When I look for activities I know that I need hooks, practice activities and extensions. If you are looking for more about how I break down teaching and modeling simple probability, check out this post. When I get back to do them, I quickly remember why they exist in the first place and just how important they really are. Hooks get kids invested in the lesson and they activate prior knowledge.

The following three activities really got my students ready to learn about probability:. They increase in complexity from one maze to the next and will give your students a lot of examples to practice simple probability. Give it a try!

As long as it is easy to understand how to play, they will play it. When you first start you have to earn tickets by choosing the best probability on a spinner wheel. The carnival theme makes it very playful. After you earn some tickets with the wheel, you can enter the carnival and play some other games. I showed the students how the game worked and then let them play for a few minutes.

Then, we discussed how each game was related to probability. Throughout the unit I let students go back and play this game when they finished something early. I had found this activity ahead of time and I was super excited to use it. So, I moved it to Wednesday.

Then, on Wednesday morning I realized I had forgotten to get the candy, again oops! I then did what all teachers do from time to time, I improvised. There was a variety of candy. I decided to have students use experimental probability to predict which candy was in a bag.

There was something like 8 purple nerds, 6 pink nerds, 2 smarties, 4 gobstoppers, and 2 purple skittles and 1 red skittles. We did this as a whole class and the everyone wrote down the experimental probability as I pulled a piece of candy out and then replaced it in the bag. One thing I would do differently is I should have done less trials. We ended up doing 22 trials and missed the chance of turning it into a proportion. But overall, it was engaging.

It illustrated for students how probability is about predicting, but not knowing exactly what will happen. This card game one was my favorite hook for this unit. I have a set of giant playing cards. One of the kids asked me where I got them and I told them I got them at a really big store where everything is really big. She asked if they had Gummi bears at this store, because she would love to see that! I had to break it to her that I actually bought them from an instructional supply company and there would be no really huge Gummi bear.

The disappointment was real. For this hook, we played a probability game as a whole class. This game pits the teacher against the whole class.Tottenham finished runner-up last season despite allowing the fewest goals in the league (26) and scoring the most (86).

For NickOne guiding factor is those taking a chance on improving or recovering teams and those who think the market principles look too strong to oppose. Nick Goff: It may lack a bit of imagination to tip the favourite but the New England Patriots are the best team, in a very weak division, and if Tom Brady stays healthy they are very likely to be appearing in another Super Bowl.

They have a young improving defence and will start the season with their big four offensive weapons on the field for the first time in more than a year. The Packers were unfortunate to meet a juggernaut Falcons team last year, and I think their defence will improve enough this year to get them over the hump.

There was a reasonable amount of consensus on this one with the Tennessee Titans getting a lot of love from the panel, although there is a pretty bold shout from Brad and a very bold shout from Jesse in amongst them.

Nick Goff: The Tennessee Titans have a huge chance to win their division and return to the playoffs for the first time since 2008. We also like Cincinnati at Betting Emporium.

This is a team that dealt with a slew of injuries a season ago along with blowing a ton of late leads. The expected improvement of Tennessee QB Marcus Mariota is one of the main reasons many of our experts fancy a decent season out of the Titans.

If the regress to the mean in games decided by seven points or less (went 1-8) last year, they should challenge for the NFC East title. Quarterback Wentz should also improve in his second season and enjoy the protection of Lane Johnson at left tackle for a full season. Johnson was suspended ten games last year, and without him Wentz posted a 48.

Jesse May: I think Head Coaches are generally underrated in the scheme of ratings and modelling. So we asked everyone what advice they would give to someone first getting started and we found some very solid adviceJesse May: Welcome to a new league of Bad Beats.

Imagine the worst sports betting bad beat you have ever taken, and then prepare yourself to get punishment and pain of a level 10 times that. But, on a more serious note, this is a betting gig with a very marginal edge. Stake in a manner that accepts that there will be a lot of variance in your results.

Also betting based on what you saw last is a terrible idea.

Jesse May: For sure. The opposite is in fact more true. Todd Furhman: The biggest mistake new NFL bettors can make is falling in love with what they saw last.


We say it all the time, no matter the sport, no team is ever as good or as bad as they looked the week prior. Try to approach each game as a blank slate taking advantage of huge overreactions in the market. A common mistake from first time NFL bettors is to not factor in the difference between numbers like 2.For each row, these new fields will be filled in automatically by parsing the value of their parent field, "date".

For example, if the latter contains the value "1969-07-14", the autogenerated columns in that row will have the values 1969, 7, 14 and 1 (because that day was Monday). When a field is detected as datetime, BigML tries to determine its format for parsing the values and generate the fields with their components.

By default, BigML accepts ISO 8601 time formats (YYYY-MM-DD) as well as a number of other common European and US formats, as seen in the table below: It might happen that BigML is not able to determine the right format of your datetime field.

In that case, it will be considered either a text or a categorical field. Once a source has been successfully created it will have the following properties. It specifies the total number of fields, the current offset, and limit, and the number of fields (count) returned. In a future version, you will be able to share sources with other co-workers or, if desired, make them publicly available. It includes a code, a message, and some extra information. See the table below.

This is the date and time in which the source was updated with microsecond precision. It follows this pattern yyyy-MM-ddThh:mm:ss. All times are provided in Coordinated Universal Time (UTC). Source Fields The property fields is a dictionary keyed by an auto-generated id per each field in the source. Before a source is successfully created, BigML.

The source goes through a number of states until all these analyses are completed. Through the status field in the source you can determine when the source has been fully processed and is ready to be used to create a dataset.

Thus when retrieving a source, it's possible to specify that only a subset of fields be retrieved, by using any combination of the following parameters in the query string (unrecognized parameters are ignored): Fields Filter Parameters Parameter TypeDescription fields optional Comma-separated list A comma-separated list of field IDs to retrieve.

In all other respects, the source is the same as the one you would get without any filtering parameter above.

To update a source, you need to PUT an object containing the fields that you want to update to the source' s base URL. Once you delete a source, it is permanently deleted. If you try to delete a source a second time, or a source that does not exist, you will receive a "404 not found" response.

However, if you try to delete a source that is being used at the moment, then BigML. To list all the sources, you can use the source base URL. By default, only the 20 most recent sources will be returned. You can get your list of sources directly in your browser using your own username and API key with the following links. You can also paginate, filter, and order your sources. Datasets Last Updated: Monday, 2017-10-30 10:31 A dataset is a structured version of a source where each field has been processed and serialized according to its type.

The possible field types are numeric, categorical, text, date-time, or items. For each field, you can also get the number of errors that were encountered processing it. Errors are mostly missing values or values that do not match with the type assigned to the column. When you create a new dataset, histograms of the field values are created for the categorical and numeric fields.

In addition, for the numeric fields, a collection of statistics about the field distribution such as minimum, maximum, sum, and sum of squares are also computed.

For date-time fields, BigML attempts to parse the format and automatically generate the related subfields (year, month, day, and so on) present in the format.
