5B Theoretical probability in single-step experiments

Theoretical probability is the actual chance or likelihood that an event will occur when an experiment takes place.

Probabilities can be expressed as:

• fractions or decimals between 0 and 1

• percentages between 0% and 100%

Let's consider these three spinners and answer the below;

1. What is the sample space for each spinner?

2. What is the probability of spinning a blue?

3. What is the P(red) for each spinner?

4. What is the P (red or green)?

5. What is the P(not blue)?
