Question

A dice is thrown, what is the probability that it is an odd prime number? Thank you!

Answer 1

`1/3` or `33 1/3%`

Explanation:

The odd prime numbers that could appear on a die roll are `3` and `5` (note that `1` is not considered a prime).

Since theer are `6` possible roll outcomes,
the probability of an odd prime is `2` out of `6` or `2/6=1/3`.
(Often probability is expressed as a percentage in which case `1/3=33 1/3%`)
