Question
(a) How many nonisomorphic (free) trees are there with 4 vertices? (b) How many solutions are there to x1+ x2+x3+X4= 20 where r4 > 10 and each x; is a natural number (0 counts as a natural number for us). (c) Let X = {1,2, 3, 4, 5}. How many relations are there on X with the property that for all x E X, x is not related to itself? (d) Give the equivalence relation on {a, b, c, d, e} whose equivalence classes give the partition P = {{a, b}, {c, d}, {e}}. (e) You are dividing 112 apples among 5 boxes. WVhat is the smallest number of apples that could appear in the box with the most apples?
