What is the theoretical probability of an event?

Back

Theoretical probability is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.

If a spinner is divided into 6 equal parts, what is the total number of outcomes?

Back

The total number of outcomes is 6.

What is the probability of spinning a number greater than 2 on a 6-part spinner?

Back

The probability is 2/3.

Front

What is the probability of spinning a number less than or equal to 2 on a 6-part spinner?

Back

The probability is 1/3.

If a die is rolled, what is the probability of getting a number greater than 4?

Back

The probability is 1/3.

Front

What is the probability of rolling a 1 on a standard 6-sided die?

Back

The probability is 1/6.

Front

What is the probability of rolling an even number on a standard 6-sided die?

Back

The probability is 1/2.

Front

What is the probability of spinning a 7 on a spinner divided into 6 parts?

Back

The probability is 0, as 7 is not an option.

Front

What does it mean if an event has a probability of 0?

Back

It means the event is impossible and will not occur.
