Simple 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 is the formula for calculating probability?

Back

Probability = (Number of favorable outcomes) / (Total number of outcomes)

Front

What does a probability of 0 mean?

Back

A probability of 0 means that the event will not occur.

Front

What does a probability of 1 mean?

Back

A probability of 1 means that the event is certain to occur.

Front

What is theoretical probability?

Back

Theoretical probability is the prediction of the likelihood of an event based on the possible outcomes.

Front

What is experimental probability?

Back

Experimental probability is the likelihood of an event based on the results of an experiment.

Front

If a die is rolled, what is the probability of rolling a 3?

Back

1/6, since there is one favorable outcome (rolling a 3) out of six possible outcomes.

Front

What is the probability of selecting a brown M&M from a bowl with 20 M&Ms?

Back

1/10, if there are 2 brown M&Ms in a total of 20.

Front

What is an unlikely event in probability?

Back

An unlikely event is one that has a probability close to 0.

Front

What is a certain event in probability?

Back

A certain event is one that has a probability of 1.
