Question

A number cube with faces numbered 1 to 6 is rolled 15 times.

In theory, how many times would you expect to roll a number less than 5?

A. 2.5

B. 5

c. 10

D. 12.5

Answer 1

10

Explanation:

there is 6 numbers on the dice. there is 4 numbers less than 5. so there is 4/6 numbers that we record. next you have to divide 15 by 6 which is 2.5 and then 2.5 times 4 which is 10.
