What is Probability?

Back

Probability is a measure of how likely an event is to occur, expressed as a number between 0 and 1.

Front

What is Theoretical Probability?

Back

Theoretical Probability is what should happen in an ideal situation, calculated using the formula: P(Event) = Number of favorable outcomes / Total number of outcomes.

Front

What is Experimental Probability?

Back

Experimental Probability is based on the actual results of an experiment, calculated as: P(Event) = Number of times the event occurs / Total number of trials.

Front

What is a Sample Space?

Back

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

Front

List the possible outcomes in the sample space for flipping a coin.

Back

Heads and Tails.

Front

What is a Favorable Outcome?

Back

A favorable outcome is the outcome that we want to happen in a probability experiment.

Front

If a bag contains 3 red and 2 blue marbles, what is the probability of picking a red marble?

Back

P(Red) = 3/5.

Front

What is the formula for calculating the probability of two independent events occurring?

Back

P(A and B) = P(A) * P(B).

Front

If you roll a die, what is the probability of rolling a number greater than 4?

Back

P(Number > 4) = 2/6 = 1/3.

Front

What is the difference between independent and dependent events?

Back

Independent events do not affect each other's outcomes, while dependent events do.
