Question

A number cube with the numbers 1, 2, 3, 4, 5, and 6 is rolled 24 times. About how many times would it be expected that a 2 or a 5 is rolled?

A.
2

B.
4

C.
6

D.
8

Answer 1

1/3 of a chance

Explanation:

Answer 2

Well, since this is expected, and not experimental, each side has a fair chance of being rolled, which is 1/6 of the time, which is 4/24 rolls. So since we have 2 numbers to expect, we do 4+4 = 8, and 8/24 = 1/3. So, getting a 2 or 5, we have a 1/3 chance, which was 8/24 before we simplified it. Hope this helped!
