Simple probability

The first instance of  is under the Probability and statistics Math Mission. This exercise practices the idea of basic probability but does not provide a model or picture to help.

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


 * 1) Roll a die: This problem asks for a probability involving rolling a single die. The student is to find the correct probability and type it into the appropriate box.Prob1.png
 * 2) Picking marbles: This problem describes a bad with some marbles and asks a probability question based on that bag. The student solves the probability and types it in the blank.Prob2.png

Strategies
This exercise is easy to get accuracy badges because there are only two types of situations that can arise at this level. Speed badges are medium because it is easy to make subtle errors, like missing a "not," if you are going too quickly.


 * 1) Even though the pictures are not drawn, you can increase your likelihood of getting questions correct if you draw your own picture of the collection of marbles, or all six possibilities that can happen when you roll a single die.
 * 2) The questions can be subtle and require careful reading more than they are difficult.
