Quantitative Reasoning Set Theory Case

Questions and Answers

1. Let U = {q, r, s, t, u, v, w, x, y, z}

A = {q, s, u, w, y}

B = {q, s, y, z}

C = {v, w, x, y, z}.

Determine A u (B n C)

Solution

U = {q, r, s, t, u, v, w, x, y, z}

A = {q, s, u, w, y}

B = {q, s, y, z}

C = {v, w, x, y, z}

First, we will find (B ( C)

B ( C = {q, s, y, z} ( {v, w, x, y, z}

B ( C = {y, z}

Now, ...
