Problem 1 (4pts): The following sets are written in the set comprehension notation. Please list theirelements explicitly, e.g., {x | x ? N, x < 4} = {0, 1, 2, 3}. {x | x ? N, x is even and x is prime} {x | x ? N, x is even and x is odd} {S | S ? Pow({0, 1, 2, 3}), #S = 2} {A | A ? Pow(N), #A = 1}Problem 2 (3pts): The set {2, 4, . . .} is ambiguous. It can mean at least three different sets. Pleasedescribe three different sets using the set comprehension notation.Problem 3 (3pts): Find the power sets of the following sets. {6, 7, 8} {?} {?, {?}, {?, {?}}}Problem 4 (8pts): Suppose A, B, C are sets. Are the following statements true? If it is true, give anexample. If it is not true, give a counter example. A ? (B ? C) = (A ? B) ? C. A × (B × C) = (A × B) × C. If A ? B and B ? C, then A ? C. A ? B ? A. …..
