Set Notation

Solve carefully: Let A = {1, 2, 3, 4} and B = {3, 4, 5}. Find A ∩ B and A ∪ B.

Show full working for: If n(U) = 40, n(A) = 23, n(B) = 19, and n(A ∩ B) = 8, find n(A ∪ B).

Answer this exam-style prompt: Let A = {1, 2, 3, 4} and B = {3, 4, 5}. Find A ∩ B and A ∪ B.

Write down the key method, then solve: If n(U) = 40, n(A) = 23, n(B) = 19, and n(A ∩ B) = 8, find n(A ∪ B).

Work this out and simplify your final answer: Let A = {1, 2, 3, 4} and B = {3, 4, 5}. Find A ∩ B and A ∪ B.

Set out your steps clearly for: If n(U) = 40, n(A) = 23, n(B) = 19, and n(A ∩ B) = 8, find n(A ∪ B).
