Question

Brian rolls a fair dice 12 times.

How many times would Brian expect to roll a number greater than 4?

Answer 1

Explanation:

If a fair dice is rolled 6 times, 2/6 times the number would be greater than 4

If rolled 12 times, then 4/12 times the number would be greater than 4

4/12 = 1/3

Answer 2

I times the 12 by 5 and divided by 2 and subtract by 12

I get 18 and I thought it is 18
