probability of rolling a composite number with one die

[Guest]

Determine the probability of rolling a composite number with one die.

First of all, what is a composite number.. and why is the answer out of 9,should it be out of 6? since there are 6 sides to a die.

Sorry Anna, but that makes no sense. Are you sure you copied the problem correctly?

A composite number is any integer greater than one that is not a prime. On a die there are two composite numbers: 4 & 6. If one tosses two dice the resulting sum can be six composite numbers: 4,6,8,9,10,12.
