P(A) = 0.60, P(B) = 0.30, and P(A and B) = 0.15. What is P(A or B)?A.0.15B.0.90C.0.18D.0.75
Question
P(A) = 0.60, P(B) = 0.30, and P(A and B) = 0.15. What is P(A or B)?A.0.15B.0.90C.0.18D.0.75
Solution
The probability of A or B can be found using the formula:
P(A or B) = P(A) + P(B) - P(A and B)
Substituting the given values:
P(A or B) = 0.60 + 0.30 - 0.15 = 0.75
So, the answer is D. 0.75.
