A 2015 study conducted by the National Center for Health Statistics found that 5151% of U.S. households had no landline service. This raises concerns about the accuracy of certain surveys, as they depend on random-digit dialing to households via landlines. Researchers pick fourfour U.S. households at random.

The Multiplication Rule says that for independent events A and B, to find the probability that both events occur, multiply the probabilities together.

Upper P left parenthesis Upper A and Upper B right parenthesis equals Upper P left parenthesis Upper A right parenthesis times Upper P left parenthesis Upper B right parenthesisP(A and B)=P(A)×P(B)

This rule can be extended to more than two independent events by multiplying the probability of each event.

The set of outcomes that are not in the event A is called the complement of A, and is denoted

Upper A Superscript Upper CAC.

The Complement Rule says that the probability of an event not occurring is 1 minus the probability that it does occur.
