What is Theoretical Probability?

Back

Theoretical Probability is what should happen in a given situation based on the possible outcomes.

Front

How many outfits can be made with 5 pairs of jeans, 8 t-shirts, and 2 pairs of shoes?

Back

80 outfits (5 jeans x 8 t-shirts x 2 shoes = 80).

Front

What is the total number of outcomes for choosing North, South, East, or West and one of the 50 states?

Back

200 outcomes (4 directions x 50 states = 200).

Front

What does P(not A) represent?

Back

P(not A) represents the probability of the event not occurring. For example, if P(A) = 1/4, then P(not A) = 3/4.

What does a tree diagram represent in probability?

Back

A tree diagram visually represents all possible outcomes of a series of events.

Front

If you flip a coin, what is the probability of getting heads?

Back

The probability of getting heads is 1/2.

Front

What is the difference between experimental and theoretical probability?

Back

Experimental probability is based on actual experiments and outcomes, while theoretical probability is based on expected outcomes.

Front

How do you calculate the probability of an event?

Back

Probability of an event = (Number of favorable outcomes) / (Total number of outcomes).

Front

What is a sample space in probability?

Back

A sample space is the set of all possible outcomes of a probability experiment.
