Events A and B are mutually exclusive with P(A) = 0.392 and P(A or B) = 0.653. Find P(B). Round your answer to 3 decimal places. Answer: Find P(not A). Round your answer to 3 decimal places. Answer:
Jacob F.
Let A and B be mutually exclusive events with P(A) = 0.34 and P(B) = 0.44. a. Calculate P(A ∩ B). (Round your answer to 2 decimal places.) P(A ∩ B) b. Calculate P(A ∪ B). (Round your answer to 2 decimal places.) P(A ∪ B) c. Calculate P(A | B). (Round your answer to 2 decimal places.) P(A | B)
