Question
Find a formula for the probability of the union of three (not necessarily mutually exclusive) events $A, B,$ and $C$.
Step 1
This is given by: \[P(A \cup B \cup C) = P(A) + P(B) + P(C) - P(A \cap B) - P(A \cap C) - P(B \cap C) + P(A \cap B \cap C)\] Show more…

Use the given information to find the indicated probability. $$ \begin{aligned} &A, B, \text { and } C \text { are mutually exclusive. } P(A)=.3, P(B)=.4\\ &P(C)=.3 . \text { Find } P(A \cup B \cup C). \end{aligned} $$

Probability and Probability Models
Match the probability formula with the correct probability name. (a) Probability of the union of two events (i) $P(A \cup B)=P(A)+P(B)$ (b) Probability of mutually exclusive events (ii) $P(A \cup B)=P(A)+P(B)-P(A \cap B)$ (c) Probability of independent events (iii) $P(A \text { and } B)=P(A) \cdot P(B)$
