Answer:

Explanation:

prime numbers are any numbers that do not have any factors other than 1 and itself.

Example: 11

factors: 1, 11

Composite numbers are any numbers that have factors besides than 1 and itself.

Example: 42

factors: 1,2,3,6,7,14,21,42

the prime numbers in the set include 29 and 31, since no numbers multiplied besides one and themselves will give the product of 29 and 31.
