What is the theoretical probability of the spinner landing on a 5?

Probability is ...

• the chance that some event will occur.

• a game that involves coins.

• a guarantee.

Theoretical Probability is?

• What Should happen

• What does happen

• What Will Happen

• What I want to Happen

Experimental Probability is:

• What Will happen 

• What actually happens

• What should happen

• What I think Happens

The number of ways an event can occur divided by the total number of outcomes is known as - 

• an event complement

• experimental probability

• an event

• theoretical probability

The extent to which something is likely to occur is known as - 

• sample space

• an event

• probability

• data

The likelihood that a single, specific event will occur is called - 

• sample space

• compound probability

• a complement

• simple probability

The ratio of the number of times an event occurred compared to the total number of trials conducted is known as - 

• theoretical probability

• experimental probability

• simple probability

• compound probability

How do we determine which event is most likely to occur?

• The event has the closest improper fraction to 1

• The event has the closest proper fraction to 1/2

• The event has the closest proper fraction to 0

• The event has the closest proper fraction to 1

In probability theory, the sum of an event (A) occurring and the same event NOT occurring (not A) is always - 

• 0

• based on the sample space

• variable

• 1
