Find the number of elements in A_1 [the union of] A_2 [the union of] A_3 if there are 100 elements in A_1, 1000 in A_2, and 10,000 in A_3 if:

a) A_1 [is a subset of] A_s and A_2 [is a subset of] A_3.

b) the sets are pairwise disjoint.

c) there are two elements common to each pair of sets and one element in all three sets.
