Claire · Answer 1

2, 3, 5, 7, 11

Step-by-step explanation:

Prime numbers only have 2 factors: 1 and themselves

What's wrong with the other number sets?

2, 4, 6, 8, 10

The only number in this set that is prime is 2.

1, 3, 5, 7, 9

The number 1 is neither prime or composite and 9 is composite.

5, 10, 15, 20, 25

All of these numbers are composite except for 5.
