Question

If you roll a dice 72 times, how many times do you expect to roll a 6?

Answer 1

Well every time you roll you have the same probability of get it 1 out of 6, so this question don't have a specific answer

Answer 2

The probability of getting a 6 is P(6) = 1/6

If you roll the dice 72 times. the expectation value = P(6) x 72

or 1/6 x 72 = 12 times
