Two dice are thrown. What is the probability that the sum of the faces equals or exceeds 10 ?

A

`1//12`

B

`1//4`

C

`1//3`

D

`1//6`

Text Solution

Verified by Experts

The correct Answer is:
D
Let E be the sum of the faces equals or exceeds
Then, `E = {(5, 5), (4, 6), (6, 4), (5, 6), (6, 5), (6, 6)}`
`therefore n(E) = 6`
Hence, `P(E) = (n(E))/(n(S)) = 6/36 = 1/6`
