Question

Unions, intersections, and complements involving 2 sets

Answer 1

A = {f, k, m, y}

B' = {k, x, y}

`A \cup B' = \{f, ~k, ~m, ~y, ~x\}`

(every element from A and any other element that B' has that A didn't)

A' = {q, x}

B' = {k, x, y}

`A \cap B' = \{x\}`

(x is the only element that both sets have)
