(enter your answer in roster notation. enter empty or for the empty set.) (b) find s, (enter your answer in roster notation. enter empty or o for the empty set.) (c) are s, and s, disjoint? yes o no (d) compare the sizes of s1 and 52: sy has elements, sz has elements, therefore the size of s the size of s2 -- is greater than is less than is equal to (e) how many elements are in s, usz? (f) what is the relation between su s2 and p(a)? os, u sy is not a subset of p(a) p(a) is not a subset of s, us2 o su s2 is a proper subset of p(a) op(a) is a proper subset of sus2 su s2 is equal to p(a)
