If a six-sided die is rolled 30 times, how many times can you expect to get a 6?
A.3
B.5
C.6
D.10

Answer 1

5 times a 6 can be expected in 30 times.

Explanation:

A die is rolled 30 times.

We have to find how many time a 6 can be expected in 30 times.

Probability of getting 6 in 1 time =
`(1)/(6)`

⇒ Probability of getting 6 in 30 time =
`(1)/(6)*30`

= 5 times

Therefore, 5 times a 6 can be expected in 30 times.

Answer 2

1/6·30=5
so your answer is b)5
