Events A and B are said to be mutually exclusive if a) P(A) = 0, b) P(B) = 0, c) P(A|B) = 0, d) P(A∩B) = 0, e) P(A) = P(B).

Step 1
If P(A)=0, it means event A never occurs. This doesn't necessarily mean that events A and B are mutually exclusive, as event B could still occur. b). If P(B)=0, it means event B never occurs. Similar to option a), this doesn't necessarily mean that events A and B Show more…

If $A$ and $B$ are any two events, the probability that exactly one of them occurs is (A) $P(A)+P(B)-2 P(A \cap B)$ (B) $P(\bar{A})+P(\bar{B})-2 P(\bar{A} \cap \bar{B})$ (C) $P(A \cap(\bar{B}))+P((\bar{A}) \cap B)$ (D) $P(A)+P(B)-P(A \cup B)$
Two events A and B are such that P(A) = 0.5, P(B) = 0.3 and P(A ∩ B) = 0.1. Calculate (a) P(A|B) (b) P(B|A)

If A and B are mutually exclusive events with P(A) = 0.295, P(B) = 0.32, then P(A | B) =
