What is probability?

Back

Probability is a measure of the likelihood that an event will occur, expressed as a number between 0 and 1.

Front

How do you calculate the probability of an event?

Back

Probability of an event = (Number of favorable outcomes) / (Total number of outcomes).

Front

What does it mean for two events to be independent?

Back

Two events are independent if the occurrence of one does not affect the occurrence of the other.

Front

What is conditional probability?

Back

Conditional probability is the probability of an event occurring given that another event has already occurred.

Front

How is conditional probability calculated?

Back

P(A|B) = P(A and B) / P(B), where P(A|B) is the probability of A given B.

Front

What is the complement of an event?

Back

The complement of an event A is the event that A does not occur, denoted as A'.

Front

How do you find the probability of the complement of an event?

Back

P(A') = 1 - P(A).

Front

What is a sample space in probability?

Back

A sample space is the set of all possible outcomes of a probability experiment.

Front

What is a favorable outcome?

Back

A favorable outcome is an outcome that satisfies the conditions of the event we are interested in.

Front

What is the probability of rolling a 3 on a fair six-sided die?

Back

P(rolling a 3) = 1/6.
