Question
P(A) = 0.50, P(B) = 0.40, and P(A and B) = 0.15.What is P(A or B)?A.0.55B.0.65C.0.75D.0.90
Solution
The probability of either event A or event B occurring can be calculated using the formula:
P(A or B) = P(A) + P(B) - P(A and B)
Substituting the given values into the formula:
P(A or B) = 0.50 + 0.40 - 0.15 = 0.75
So, the answer is C. 0.75.
