Probability
For mutually exclusive events A and B, P(A ∪ B) equals
Select the correct option:
Solution
P(A) + P(B)
- Definition: Mutually exclusive events cannot occur at the same time (A∩B=∅).
- General Addition Rule: P(A∪B)=P(A)+P(B)−P(A∩B).
- Application: Since the intersection is impossible, P(A∩B)=0.
- Result: P(A∪B)=P(A)+P(B).
