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}. list the elements in the set. a ∩ (b ∪ c)a) {q, s, w, y}b) {q, y, z}c) {q, s, u, w, y, z}d) {q, r, w, y, z}

  a) {q, s, w, y}

Step-by-step explanation:

B ∪ C = {q, s, y, z} ∪ {v, w, x, y, z} = {q, s, v, w, x, y, z} . . . . elements in either set

A ∩ (B ∪ C) = {q, s, u, w, y} ∩ {q, s, v, w, x, y, z} = {q, s, w, y} . . . . elements in both sets (matches selection A)

huh? im pretty sure it is in 199
