Document Summary

If n(u ) = 70, n(a) = 15, n(a b c) = 10 and n(ac b c) = 20, nd n(ac b). Solution: we see that n(ac) = n(u ) n(a) = 70 15 = 55. And then by partitioning ac we get n(ac) = n(ac b) + n(ac + b c) n(ac b) = n(ac) n(ac b c) = 55 20 = 35. Bill is a rst-year social science student at king"s who is taking math 1228 this term. Solution: we are told that bill is in f and is in ss so he"s in f ss and is not in m , so he"s in m c. Since bill is in f he"s also in the union of f with any set, whether or not he"s in that other set, so he"s in. That is, bill is in m ss, and so he is not in (m ss)c.
