$\huge\mathcal{\fbox{\fbox{\pink{Answer}}}}$

“Composite” as in “not a prime”? There are only two such numbers on a six-sided die, 4 and 6, so the probability of that happening is 1/3.

Note that I’m including 1 in the list of non-composite numbers, even though it is not a prime. Otherwise the probability of getting a composite number is 1/2.
