Let A and B be two disjoint events such that P(A) = 0.47 and P(B) = 0.3.
What is P(A or B)?
2 answers:
<h3>
Answer: 0.77</h3>
Work Shown:
P(A or B) = P(A) + P(B)
P(A or B) = 0.47 + 0.30
P(A or B) = 0.77
Notes:
- The formula only works if A and B are disjoint, aka mutually exclusive
- If A and B are not disjoint, then use this formula: P(A or B) = P(A) + P(B) - P(A and B)
Answer:
P(A or B) = 0.77
