Question

If C = {integers divisible by 2 from 1 to 12} and D = {integers divisible by 4 from 1 to 16}, what is C ∩ D?

{4, 8, 12}

{2, 4, 6, 8, 10, 12, 16}

{8, 12}

{ }

Answer 1

C∩D means whatever is in C AND D....

so numbers that are divisible by 2 from 1 to 12 AND divisible by 4 from 1 to 16

Answer 2

which is 4 8 and 12

so {4,8,12}
