Question

Which of the following is a subset of the set
A: {integers divisible by 3 from 1 to 25}
Answer
{6, 9, 12, 15}
{0, 3, 6, 9 …}
{integers divisible by 6 from 1 to 36}
{24, 27, 30, 33}

Answer 1

{0, 3, 6, 9 …} is not since it's an infinite set

Answer 2

{integers divisible by 6 from 1 to 36} is not because we're dealing with 3, not 6

Answer 3

{24, 27, 30, 33} is not because 27, 30, and 33 are greater than 25

Answer 4

and it turns out that the answer is actually in fact {6, 9, 12, 15} since all of these numbers are a) multiples of 3, and b) lie in the range from 1 to 25

Answer 5

so its the first one

Answer 6

exactly
