Front

What does it mean if two events are equally likely?

Back

It means that the probability of each event occurring is the same.

Front

How do you calculate the probability of an event?

Back

Probability is calculated as the number of favorable outcomes divided by the total number of possible outcomes.

Front

What is a spinner in probability?

Back

A spinner is a tool used in probability experiments that can land on different outcomes, often represented in sections.

Front

If Spinner #1 has 4 equal sections and Spinner #2 has 2 equal sections, what is the probability of landing on a specific section for each?

Back

Front

What does it mean for one spinner to be twice as likely as another?

Back

It means that the probability of landing on a specific outcome on that spinner is double the probability of landing on the same outcome on the other spinner.

Front

What is a sample space in probability?

Back

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

Front

What is the probability of selecting an apple if there are 3 apples and 7 oranges in a basket?

Back

Front

What is the probability of selecting an orange in the same scenario?

Back

Front

What does it mean if the probability of an event is 0?
