Definitions:

Conditional Probability (P(B | A))

The probability of an event B occurring given that event A has already occurred.

Mutually Exclusive

Describes events that cannot occur at the same time, meaning the occurrence of one event excludes the possibility of the other event happening.

P(A ∩ B)

The probability of the intersection of events A and B, representing the likelihood that both events occur simultaneously.

P(A ∪ B)

Represents the probability of the occurrence of at least one of two events, A or B, including the case where both events occur simultaneously.
