Probabilities of compound events

The first instance of  is under the Probability and statistics Math Mission. This exercise practices finding the probability of an event that has more than one part to it.

Types of Problems
There is one type of problem in this exercise:


 * 1) Use picture, find probability: This problem has a diagram, chart or other visual aid drawn and asks for the probability of a particular event. The student types in the correct probability in the slot provided.Comev1.png

Strategies
This exercise is easy to get accuracy badges because the visual aid is there for assistance. The speed badges are medium, I am guessing due to time tolerances. Research was only able to get the very first basic one.


 * 1) Fractions do not need to be reduced.
 * 2) Use the picture. If you read the event carefully there is no good reason to get this one wrong unless you are misreading the problem.
