विकल्प

• `5/216`

• `1/6`

• `1/36`

• `1/49`

Answer 1

Three dice are thrown simultaneously. The probability of obtaining a total score of 5 is `underlinebb(1/36)`.

Explanation:

Total no. of cases when three dice are thrown

= 6 × 6 × 6

n(S) = 216

Number of cases where getting sum of 5

= {(1, 1, 3), (1, 3, 1), (1, 2, 2), (2, 1, 2), (2, 2, 1), (3, 1, 1)}

n(E) = 6

Probability of obtaining a total score of 5

`P(E) = (n(E))/(n(S))`

= `6/216`

= `1/36`
