Question #1:

A union B consists of all those that are in set A as well as all those that are in set B (just don't count

anyone twice:  8, 14, 17, 16, 9, 15.

A intersect B consists of only those which are in the overlap of A and B (14, 17 ).

A' consists of all the numbers that aren't in A (16, 9, 15, 13, 10, 11, 12)

The probability of randomly choosing a number that is in A' is the number in A divided by the total

number of numbers; you can do this!
