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,yz}. List the elements in the set.A'uB

I need help with this question.

2. Let A = {1,2, 3}, B = {4, 5, 6}, C = {7,8, 9}. Consider the relations R from A to B, S from B to C, and T on A. R = {(1, 5), (2, 4), (1, 6)} S = {(4, 8), (5, 7), (6, 8), (6, 9)} Т 3 {(1,2), (2, 3), (3, 1), (1, 1), (2, 2), (3, 3)} Find the following relations (a) Find the compositions Ro S, T o R, T o T. (b) Find the matrices MR, Ms, MT, MTOT, MTOR and MRos of the respective relations R, S, т, То Т, То R, and Ro S.

Let U= {1,2,3,4,5,6,7,8,9}  A= {2,4,6,8}  B= {1,2,3,4} and C= {5,7,9}  Give a set, D, that is equivalent to C, but not equal to C.  I am confused on the difference and how to proceed with this.

5) Let U = {0,1,2,3,4,5,6,7,8,9,10}; A = {0,1,2,3,5,8}; B = down the elements in the following sets. (a) AUB (b) BUC (c) BC (d) (A' n C) UB (e) n((A UC) n B) = {0,2,4,6}; C = {1,3,5,7}. Write

Let U={1,2,3,6,8,9,10,12,13}, X= {2,6,9,12}, Y = {2,3,6,8,9), and Z={1,2,3,12,13}. List the members of the given set, using set braces. (XNY')U(Z'NY') (XNY')u(Z'NY') = {} (Use a comma to separate answers as needed.)

Let U={a, b, c, d, e, f, g, h, i, j, k}. Let A={d, f, g, h, i, k}. Let B={a, d, f, g, h}. Let C={a, c, f, i, k}.   Determine A ∩ C.
