Probability Complement of Event

All of the possible outcomes in the sample space that are not part of the event are called

• Experimental probability

• P(event)

• Theoretical probabilty

• Complement of an event

The probability of an event not happening is known as

• experimental probability

• theoretical probability

• sample space

• compliment of an event

The probability of an event not happening is known as the

• experimental probability

• theoretical probability

• sample space

• compliment of an event

Identify the notation

• probability of the event A

• probability of the compliment of event A
