5. a) A and B are the subsets of a universal set U. If n(U) = 75, n(A) = 40, n(B) = 60 ai Ac B then illustrate these information in a Venn-diagram and find:
(i) n(A UB)
(ii) n(A n B)
(iii) n(Only B)
(iv) n(A U B)

choice b is correct

step-by-step explanation:

we have been given the following system of linear inequalities;

we are required to graphically determine the solution to these system of inequalities. using a graphing tool, the solution is as shown in the attachment below;
