What is a probability model?

Back

A probability model is a mathematical representation of a random phenomenon, describing the likelihood of different outcomes.

Front

What is the sample space in probability?

Back

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

How do you calculate the probability of an event?

Back

Probability of an event = (Number of favorable outcomes) / (Total number of possible outcomes).

Front

What does it mean if an event is certain?

Back

An event is certain if it will definitely happen, with a probability of 1.

Front

What does it mean if an event is impossible?

Back

An event is impossible if it cannot happen, with a probability of 0.

Front

What is an even number?

Back

An even number is an integer that is exactly divisible by 2.

Front

What is a spinner in probability experiments?

Back

A spinner is a circular device divided into sections, each representing a different outcome, used to generate random results.

Front

What is the probability of rolling an even number on a standard die?

Back

The probability is 3/6 or 1/2, since the even numbers are 2, 4, and 6.

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

What is the difference between independent and dependent events?

Back

Independent events do not affect each other's outcomes, while dependent events do.
