Question

Two dices are thrown simultaneously. The probability of obtaining a total score of 8 is

Options

• `5/36`

• `1/6`

• `1/9`

• `7/36`

Answer 1

`5/36`

Explanation:
n(s) = 6 x 6 = 36
E = event of getting total score of 8
= {(2, 6) (6, 2) (3, 5) (5, 3) (4, 4)}
⇒ n(E) = 5
∴Required probability, p(E) = `(n(E))/(n(S))=5/36`
