The Set A’∪ B = { r, t, v, x, z, q, s, y, z }
We have the following sets -
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}
We have to determine the set represented by - A' ∪ B.
A set is a collection of elements or numbers or objects, represented within the curly brackets { }. For example: {1,2,3,4} is a set of numbers.
According to question, we have -
U = {q, r, s, t, u, v, w, x, y, z} (Universal Set)
A = {q, s, u, w, y}
B = {q, s, y, z}
C = {v, w, x, y, z}
Consider Set A = {q, s, u, w, y}
A' = U - A = {q, r, s, t, u, v, w, x, y, z} - {q, s, u, w, y} = { r, t, v, x, z }
and Set B = {q, s, y, z}
Now -
A' ∪ B = { r, t, v, x, z } ∪ {q, s, y, z} = { r, t, v, x, z, q, s, y, z }
Hence, the Set A’∪ B = { r, t, v, x, z, q, s, y, z }
