I know I posted this question already ,but I posted the wrong one....

Sets A,B and C are subsets of U.

U= positive integers less than 16
A= prime numbers
B= factors of 36
C= multiples of 4

(A intersect B)' INTERSECT C {?}

I meant INTERSECT not union!

My answer: 4,8,12

From the help I've seen given on this, you should not still be having troubles. That said, however,

A = {2,3,5,7,11,13}
B = {1,2,3,4,6,9,12}
C = {4,8,12,16}

(A∩B) = {2,3}
(A∩B)' = {1,4,5,6,7,8,9,10,11,12,13,14,15,16}
(A∩B)'∩C = {4,8,12,16}
Note that C⊆(A∩B)'

What process did you use to get your answer?
