प्रश्न

A dice is thrown once. Find the probability of getting a number less than 3.

बेरीज

उत्तर

In throwing a dice, total possible outcomes = {1, 2, 3, 4, 5, 6} 

n(S) = 6

On a dice, number less than 3 = {1, 2} 

n(E) = 2

Probability of getting a number less than 3

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

= `2/6`

= `1/3`
