Conditional Probability Flashcards

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

P(A | B) = P(A ∩ B) / P(B), where P(B) ≠ 0.

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

The set of outcomes that are in both event A and event B.

If events A and B are independent, P(A | B) = P(A).

A diagram used to represent conditional probabilities by showing the sequence of events and their probabilities.

A table used to organise data and calculate conditional probabilities by focusing on specific rows or columns.

A diagram that shows the relationships between events and can be used to calculate probabilities, including conditional probabilities.

If events A and B are mutually exclusive, P(A | B) = 0 because they cannot occur together.

Conditional probability can be estimated using relative frequency from experimental data.
