A) Quantity A is greater.
B) Quantity B is greater.
C) The two quantities are equal.
D) The relationship cannot be determined from the information given.
Let's list some prime numbers: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, . . . etc
Notice that 2 is the only prime number divisible by 2
If any other number in the list were divisible by 2, then that number would NOT be prime.
So, there's only 1 prime number that's divisible by 2
Now notice that 3 is the only prime number divisible by 3
If any other number in the list were divisible by 3, then that number would NOT be prime.
So, there's only 1 prime number that's divisible by 3
We get:
QUANTITY A: 1
QUANTITY B: 1
Answer: C
Cheers,
