jamesj · Answer

The number divisible two 2 between 2 and 10 are
D = {2, 4, 6, 8, 10}
Therefore $ C \cap D = $ what?

anonymous · Answer

I think its D.?

jamesj · Answer

$ C \cap D $ means the intersection of those two sets: $ C \cap D $ is the set whose members are all members of both $ C $ and $ D $.

jamesj · Answer

So, no: option d is not the right answer.

jamesj · Answer

The intersection of
C = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10 } and
D = {2, 4, 6, 8, 10}
is .....
