# Question: Prove Theorem 1 1 6 Theorem 1 1 6 If A B and C are any

Prove Theorem 1.1-6.

Theorem 1.1-6

If A, B, and C are any three events, then P(A ∪ B ∪ C) = P(A) + P(B) + P(C) − P(A ∩ B)

−P(A ∩ C) − P(B ∩ C) + P(A ∩ B ∩ C). Write A ∪ B ∪ C = A ∪ (B ∪ C)

Theorem 1.1-6

If A, B, and C are any three events, then P(A ∪ B ∪ C) = P(A) + P(B) + P(C) − P(A ∩ B)

−P(A ∩ C) − P(B ∩ C) + P(A ∩ B ∩ C). Write A ∪ B ∪ C = A ∪ (B ∪ C)
