Question

If Monique rolls the number cube 12 times, how many times she expect a number greater than 4 to be rolled?

Answer 1

Chance of getting number greater than 4 on one roll:

Either getting a 5 or 6

2/6 probability

2/6 = 1/3

If we roll the cube 12 times, the probability of getting a number greater than 4 is 1/3 of the time

12 * 1/3 = 4

She is expected to get a number greater than 4, 4 times
