Question

If C = {integers divisible by 2 from 1 to 20} and D = {integers divisible by 6 from 1 to 25}, what is C ∩ D?

Answer 1

it is all integers divisible by both 2 and 6.

Answer 2

C = {2, 4, 6, 8, 10, 12, 14, 16, 18, 20}
D = {6, 12, 18, 24}

C ∩ D (The set where C and D intersect) = {6, 12, 18, 24}

Answer 3

Actually, made a mistake C ∩ D (The set where C and D intersect) = {6, 12, 18}

Answer 4

24 is not in set C

Answer 5

ok thank you
