Experimental and Theoretical Probability

Describe what EXPERIMENTAL PROBABILITY is.

• What DID happen during the experiment

• What SHOULD happen in an experiment

Describe what THEORETICAL PROBABILITY is.

• What DID happen in an experiment

• What SHOULD happen in an experiment

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 possible result of a situation or experiment is called what?

• Event

• Sample Space

• Probability

• Outcome

A single outcome or a group of outcomes is called

• Probability

• Event

• Sample Space

• Complement of an event

The set of all possible outcomes refers to the

• Sample Space

• Outcome

• Compliment of the event

• Experimental Probability

P(event) should be spoken as

• P times event

• Prevent

• the probability of an event

• the event multiplied by P

• Complement

Which table shows an experimental probability of landing on tails that is closest to the theoretical probability of landing on tails?

• 
• 
• 
• 

Determine the type of probability:

The probability of flipping tails is 1/2, or 50%, since the sides of a coin have 1 tails and 1 heads.

• Theoretical Probability

• Experimental Probability

Determine the type of probability:

A spinner has 4 equal-sized spaces labeled A, B, C, and D.

The chance of landing in any of the spaces is 1/4, or 25%.
