Answer:

D. Both Tyler and Mary are incorrect. The prime numbers in the seventies are 71, 73, and 75

Step-by-step explanation:

Tyler is incorrect because prime numbers are numbers that can only be divided by itself and one, and an example would be the number 77 (odd), it's a composite number BECAUSE it can be divided not only by itself, BUT with other numbers such as 11 and 7. Mary is incorrect because the numbers 71, 73, and 75 are prime !

I hope you understand it a bit more now ! ^^
