AP Stats Chapter 5 Probability

Front

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

What does it mean for two events to be independent?

Back

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

Front

What does it mean for two events to be mutually exclusive?

Back

Two events are mutually exclusive if they cannot occur at the same time; the occurrence of one event means the other cannot occur.

Front

What is the Law of Large Numbers?

Back

The Law of Large Numbers states that as the number of trials increases, the experimental probability of an event will get closer to the theoretical probability.

Front

How do you simulate a random event using digits?

Back

You can assign digits to outcomes; for example, using 0-9 to represent different outcomes based on their probabilities.

Front

What is a two-way table?

Back

A two-way table is a statistical table that displays the frequency distribution of two categorical variables.

Front

What is the probability of an event?

Back

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

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 minus the probability of 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 random variable?

Back

A random variable is a variable whose possible values are numerical outcomes of a random phenomenon.
