Possible Outcomes and 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 likelihood of two or more related events occurring is called - 

• compound probability
• theoretical probability
• simple probability
• experimental probability

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 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

A set of all possible outcomes is known as - 

• a list
• a complement
• a sample space
• an event

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

Which of the following expressions would be used to calculate the complement of an event occurring?

• P(event) - 1
• P(event 1) x    P(event 2)
• P(event)/possible outcomes
• 1 - P(event)

P(A) + P(not A) = 1

• True
• False
