Question

If C = {integers divisible by 2 from 1 to 25} and D = {integers divisible by 6 from 1 to 30}, what is C ∩ D?

{ }

{2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 30}

{6, 12, 18, 24, 30}

{6, 12, 18, 24}

Answer 1

those which are divisible by 2 and 6

Answer 2

C = {integers divisible by 2 from 1 to 25}

translates to

C = {2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24}

Answer 3

Do the same thing to translate set D

Answer 4

C ∩ D means the set containing elements common to the 2 sets C and D

Answer 5

{6,12,18,24}
write the two sets seperately
then take the common elements(no.s)and put them in the set

Answer 6

so the answer is C?

Answer 7

D

Answer 8

It's not C because 30 is NOT in set C

Answer 10
