Front

What is the range of probability for any event?

Back

The probability of any event must be a number between 0 and 1, inclusive.

Front

What must the sum of all probabilities in a sample space equal?

Back

The sum of all the probabilities of all outcomes in the sample space must be exactly 1.

Front

How is the probability of an event calculated?

Back

The probability of an event is the sum of the outcomes in the sample space which make up the event.

Front

What is a sample space in probability?

Back

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

Front

Define an event in probability.

Back

An event is a specific outcome or a set of outcomes from a sample space.

Front

What is the complement of an event?

Back

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

Front

What is an independent event?

Back

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

Front

What is a dependent event?

Back

Two events are dependent if the occurrence of one event affects the probability of the other event.

Front

What is the formula for calculating the probability of independent events?

Back

P(A and B) = P(A) * P(B) for independent events A and B.

Front

What is the formula for calculating the probability of dependent events?

Back

P(A and B) = P(A) * P(B|A) for dependent events A and B.
