Question

Two dice are rolled together. The probability of getting the sum of the two numbers to be more than 10, is ______.

Options

• `1/9`

• `1/6`

• `7/12`

• `1/12`

Answer 1

Two dice are rolled together. The probability of getting the sum of the two numbers to be more than 10, is `bbunderline(1/12)`.

Explanation:

When two dice are rolled together then sample space

S = {(1, 1) (1, 2) (1, 3)......(6, 6)}

n(S) = 36

The sum of two numbers to be more than 10

A = {(6, 5) (5, 6) (6, 6)}

n(A) = 3

∴ P(A) = `3/36`

= `1/12`
