Question

In a box contains number stickers 1,2,3,4,5. If you pick one without looking, find the probability of getting a even number

Answer 1

The even numbers in the box is 2 and 4. So

`n(x)=2`

The total possible outcomes are 1,2,3,4, 5. So,

`n(T)=5`

The formula for the probability is,

`P=(n(x))/(n(T))`

Substitute the values in the formula to obtain the probabiliy for the even number.

`P=(2)/(5)`

So answer is 2/5.
