Probability Concepts

These flashcards cover essential vocabulary and key concepts related to probability, including rules, notation, and graphical representations.

Multiplication Rule

The product of the probabilities of two independent events.

Independent Events

Events where the outcome of one event does not affect the outcome of another event.

P(AUB)

Symbolizes the probability of A or B occurring, also known as the union of A and B.

P(ANB)

Symbolizes the probability of both A and B occurring, also known as the intersection of A and B.

Joint Probability

The probability of two events happening at the same time.

Venn Diagrams

Visual tools used to represent and calculate probabilities for compound and overlapping events.

Conditional Probability

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

P(A|B)

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

P(B|A)

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

Caution in Conditional Probability

Always remember that P(A|B) is not the same as P(B|A); they represent different probabilities.
