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

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

add the numbers under frequency to find the total number:

5 + 8 +7 + 4 + 0 +1 = 25

the answer is 25.
