What is probability?

Back

Probability is a measure of the likelihood that an event will occur, expressed as a number between 0 and 1.

What is experimental probability?

Back

Experimental probability is the ratio of the number of times an event occurs to the total number of trials or experiments conducted.

Front

What is theoretical probability?

Back

Theoretical probability is the ratio of the number of favorable outcomes to the total number of possible outcomes in a given situation.

Front

How do you calculate the probability of an event?

Back

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

If a bag contains 3 red marbles, 2 blue marbles, and 4 yellow marbles, what is the probability of drawing a blue marble?

Back

Probability of drawing a blue marble = 2/(3+2+4) = 2/9.

Front

What is the probability of pulling a green marble from a bag containing 8 marbles, 2 of which are green?

Back

Probability = 2/8 = 1/4.

Front

What is a sample space in probability?

Back

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

Front

What is a favorable outcome?

Back

A favorable outcome is an outcome that satisfies the conditions of the event we are interested in.

If you roll a die, what is the probability of rolling an even number?

Back

Probability of rolling an even number = 3/6 = 1/2.

What is the probability of selecting a large green shirt from a selection of shirts that includes small, medium, and large sizes in red, blue, green, and white?

Back

Probability = 1/(3 sizes * 4 colors) = 1/12.
