Theoretical Probability

What is Theoretical Probability?

Back

The ratio of favorable outcomes to the total number of possible outcomes.

Front

How do you calculate the theoretical probability of an event?

Back

Divide the number of favorable outcomes by the total number of possible outcomes.

Front

If a spinner has 8 equal sections, and 3 of them are orange or red, what is the theoretical probability of landing on orange or red?

Back

3/8

Front

What is the total number of possible outcomes when spinning a spinner with 4 equal sections?

Back

4

Front

What is the theoretical probability of rolling an 8 on a standard number cube (1-6)?

Back

0, because an 8 is not a possible outcome.

Front

In a set of numbers from 1 to 20, how many numbers are divisible by 5?

Back

There are 4 numbers (5, 10, 15, 20) that are divisible by 5.

Front

What is the theoretical probability of picking a number divisible by 5 from 1 to 20?

Back

1/5, because there are 4 favorable outcomes out of 20 possible outcomes.

Front

What is an example of a favorable outcome in a probability experiment?

Back

A favorable outcome is any outcome that satisfies the condition of the event being measured.

Front

If a spinner has 4 colors, what is the probability of landing on any one specific color?

Back

1/4, since there are 4 equal sections.

Front

What does it mean if an event has a theoretical probability of 1?

Back

It means the event is certain to occur.
