Question

Choose the correct alternative answer for the following question.

A die is rolled. What is the probability that the number appearing on upper face is less than 3 ?

Options

• `1/6 `

• `1/3 `

• `1/2`

• 0

Answer 1

Sample Space (S) = {1, 2, 3, 4, 5, 6}
∴ n(S) = 6
Event A: a number is less than 3
A = {1, 2}
∴ n(A) = 2

`therefore P (A) =(n(A))/(n(S)`

`=2/6`

`=1/3`
