If events A and B are mutually exclusive, then P(A|B) is always equal to zero. TRUE AACSB: Reflective Thinking Bloom's: Knowledge Difficulty: Hard Topic: Probability & Mutually Exclusive Events 8. If events A and B are independent, then P(A|B) is always equal to zero. FALSE AACSB: Reflective Thinking Bloom's: Knowledge Difficulty: Medium Topic: Probability & Independence 1-279 Chapter 01 - An Introduction to Business Statistics 9. If events A and B are mutually exclusive, then P(A TRUE B) is always equal to zero. AACSB: Reflective Thinking Bloom's: Knowledge Difficulty: Easy Topic: Probability & Mutually Exclusive Events 10. Events that have no sample space outcomes in common, and, therefore cannot occur simultaneously are referred to as independent events.
