I worked this problem, but I just want to check and make sure I did it correctly.

Given U = {15,16,17,18,19,20,21,22,23,24,25}
A = {16,18,20,22}
B = {17,19,20,23,24}
Find A'¿B'. Finding A', then B' then find their intersection.

    What did you get?

    Don't know what "character encoding" your browser uses, but in Western-ISO8859-1, you can put
    ∩ as & c a p ;
    ∪ as & c u p ;
    (do not type the intervening spaces)
