Describing subsets of sample spaces

The first instance of  is under the 4th Grade Math Mission. This exercise practices being able to select an even from a complete probability space and recognizing how the sizes of different sets of events effect probability.

Types of Problems
There are two types of problems in this exercise:


 * 1) Settle disagreement: This problem describes a single situation in which two people disagree on a particular probability. The student is expected to settle the argument correctly by determining which party has the correct analysis of the probability.Subspace1.png
 * 2) Describe subset: This problem shows a sample space with some selection of the outcomes highlighted. The student is asked to select all complete and accurate descriptions of the highlighted outcomes from a multiple select list.Subspace2.png

Strategies
This exercise is medium to get accuracy badges because it takes some time to read options carefully and the probability calculations can be subtle. The speed badges should be considered hard because of the time needed to be careful and current speed requirements.


 * 1) On Settle disagreement if there is a sample space drawn you can use it to help you get the question correct, though it will not necessarily help you on speed.
 * 2) On Describe subset there will never be a no solution. At least one of the statements holds.
 * 3) Be careful on Describe subset. You need to select the options that fully describe the set, so all the highlighted options have to satisfy your selection AND your selection covers all the highlighted options.
