a. Given two subsets A and B of the Universal set U. State the Sum Rule for two sets A
and B.
b. Use the Sum Rule for two sets to show that
|A UB UC| = |A| + |B| + |C] – |A U B| – |A U C| – |B U C| + |A n BnC|

c. Let U be the set of 35 students participating in the sports of Football, Basketball or
volleyball. 6 of these students participate in all the sports and 7 of them do not
