Question

When you roll a standard number cube once, what is the probability of rolling a number divisible by 3?

Answer 1

`(1)/(3)`

Explanation:

On a standard cube there are the numbers 1, 2, 3, 4, 5, 6

Only 2 are divisible by 3, that is 3 and 6, hence

P(divisible by 3 ) =
`(2)/(6)` =
`(1)/(3)`
