Rework problem 12 from section 1.2 of your text, about disjoint subsets A and B of a universal set U, except assume that n(U)=135, n(A)=50, and n(B)=45. Then n(A′ ∪ B)=

QUESTION 10 Consider the following statements: T(x, y): "x eats y". A(x): "x is wise". S(x): "x is hungry". F(y): "y is fat". H(y): "y is healthy".
