Question

Two dice are rolled together. The probability of getting an outcome (a, b) such that b = 2a is ______.

Options

• `1/6`

• `1/12`

• `1/36`

• `1/9`

Answer 1

Two dice are rolled together. The probability of getting an outcome (a, b) such that b = 2a is `underlinebb(1/12)`.

Explanation:

Total possible outcomes = 36

Possible favourable outcomes = 3

{(1, 2), (2, 4), (3, 6)}   ...(∵ b = 2a)

Required probability = `3/36 = 1/12`
