Discrete Probability Union and Subset

Suppose P (A) = 0.33, P(B) = 0.38, P(C) = 0.39, P(A ∩ B) = 0.13, P(A ∩ C) = 0.11, P(B ∩ C) = 0.21, and P(A ∩ B ∩) = 0.08. Find P(A ∪ B ∪ C).

P(A ∪ B ∪ C) = P(A) + P(B) + P(C) - P(A ∩ B) - P(A ∩ C) - P(B ∩ C) + P(A ∩ B ∩ C)

P(A ∪ B ∪ C) = 0.33 + 0.38 + 0.39 - 0.13 - 0.11 - 0.21 + 0.08 = 0.73
