Question

If you roll a number cube, what is the probability that you will roll an even number?

Answer 1

`(1)/(2)`

Explanation:

Probability is calculated as

P =
`(favourable outcome)/(number of outcomes)`

A favourable outcome is an even number , that is 2, 4, 6 , a total of 3

number of outcomes = 6 , that is 1, 2, 3, 4, 5, 6

Then

P( even number) =
`(3)/(6)` =
`(1)/(2)`
