Probability Terminology

Front

What is a simple event in probability?

Back

A simple event is an event that has only one possible outcome.

Front

Define an event in the context of probability.

Back

An event is a set of one or more outcomes.

Front

What are independent events?

Back

Independent events are two events that do not affect the outcome of each other.

Front

What happens to the probability of event B if event A is independent?

Back

The probability of B is not affected by whether A happens.

Front

What are dependent events?

Back

Dependent events are events in which one event affects the outcome of another.

Front

What is the probability of a simple event?

Back

The probability of a simple event is calculated as the number of favorable outcomes divided by the total number of possible outcomes.

Front

What is the difference between independent and dependent events?

Back

Independent events do not influence each other's outcomes, while dependent events do.

Front

How do you calculate the probability of two independent events occurring together?

Back

The probability of two independent events A and B occurring together is calculated by multiplying their individual probabilities: P(A and B) = P(A) * P(B).

Front

What is a compound event?

Back

A compound event is an event that consists of two or more simple events.

Front

What is the complement of an event?

Back

The complement of an event A is the set of all outcomes in the sample space that are not in A.
