Question

A fair die is rolled 30 times. How many times would you expect a 2 or a 6 to be rolled?n

Answer 1

At least 10 or 5 times.

Explanation: 2 and 6 gives a 2/6 chance of landing on these numbers when rolled once but if it rolled 30 times, the chance would be 60/180 which means that it should be expected to have landed on either of those numbers at least 10 or 5 times.

Answer 2

6 sides on a die:
6*5= 30
5*2 (2 is both numbers) = 10
Probability= 2/6 so 5*2 =10

10
