What is the probability of the intersection of two mutually exclusive events?

• A. P(A ∩ B) = 1
• B. P(A ∩ B) = P(A) + P(B)
• C. P(A ∩ B) = 0
• D. P(A ∩ B) = P(A) - P(B)

Answer: (C)

When dealing with mutually exclusive events, it is essential to understand that these events cannot occur at the same time. This means that if one event happens, the other cannot occur. In terms of probability, the intersection of two mutually exclusive events, denoted as (A) and (B), is described mathematically as (P(A \cap B)), which represents the probability of both events happening simultaneously.

Since (A) and (B) cannot occur together, the probability of their intersection is always zero. Hence, the correct answer states that (P(A \cap B) = 0), indicating that the likelihood of both events occurring at the same time is nonexistent.

Other provided options, such as those suggesting non-zero probabilities or incorrect mathematical operations involving probabilities, do not accurately represent the properties of mutually exclusive events. This distinction is crucial for grasping the foundational concepts of probability theory. Understanding that mutually exclusive events result in an intersection probability of zero is essential for solving related probability questions correctly.
