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 is a Venn diagram?

Back

A Venn diagram is a visual representation of the relationships between different sets, often used to illustrate probabilities.

Front

What does it mean for an event to be independent?

Back

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

Front

What is the complement of an event?

Back

The complement of an event A is the event that A does not occur, and its probability is 1 - P(A).

Front

What is a sample space?

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

How do you express probability as a fraction?

Back

Probability can be expressed as a fraction by dividing the number of favorable outcomes by the total number of outcomes.

Front

What is the probability of an event that is certain to happen?

Back

The probability of an event that is certain to happen is 1.

Front

What is the probability of an impossible event?

Back

The probability of an impossible event is 0.
