Your friend says she has an unfair number cube: the probability of getting a one or a six is 1/3 for each, and the probability of getting a two, three, four, or five is 1/12 for each. You want to test her statement. If you roll the number cube 96 times, what are the expected values for each number on the number cube

Answer:

See below.

Step-by-step explanation:

Expected number = probability x 96 (the number of rolls)

Outcome    Probability    Expected Value

1                   1/3                  (1/3)(96) = 32

2                  1/12                 8

3                  1/12                 8

4                  1/12                  8

5                  1/12                  8

6                  1/3                    32
