Stats- Chapter 4 Review

Front

What is empirical probability?

Back

Empirical probability uses results from an experiment to calculate the likelihood of an event occurring.

Front

Can an event and its complement occur at the same time?

Back

No, an event and its complement cannot occur at the same time.

Front

What does _nP₀ equal?

Back

1

Front

What is the set of all possible outcomes of a probability experiment called?

Back

Sample space.

Front

What is the formula to calculate the probability of 'At Least one' event occurring?

Back

1 - P(none).

Front

Define sample space in probability.

Back

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

Front

What is the complement of an event?

Back

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

Front

What is the difference between theoretical and empirical probability?

Back

Theoretical probability is based on the possible outcomes in a perfect world, while empirical probability is based on actual experiments.

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.

Front

How do you calculate the probability of two independent events occurring?

Back

Multiply the probabilities of each event: P(A and B) = P(A) * P(B).
