Question

If I roll a die what is the probability of rolling an even number?

Answer 1

1/2

Explanation:

A standard dice has six sides numbered: 1,2,3,4,5, and 6.

• The total number of sides = 6

,

• The number of sides numbered with an even number = 3

To find the probability of rolling an even number, divide the number of even sides by the total number of sides.

`P(\text{rolling an even number)}=(3)/(6)=(1)/(2)`

The probability of rolling an even number is 1/2.
