Probability overview

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 the range of probability values?

Back

Probability values range from 0 (impossible event) to 1 (certain event).

Front

What does it mean if an event has a probability of 0?

Back

An event with a probability of 0 is considered impossible and will not occur.

Front

What does it mean if an event has a probability of 1?

Back

An event with a probability of 1 is considered certain and will definitely occur.

Front

What is experimental probability?

Back

Experimental probability is the probability based on the actual results of an experiment, calculated as the number of successful outcomes divided by the total number of trials.

Front

What is theoretical probability?

Back

Theoretical probability is the probability calculated based on the possible outcomes in a perfect scenario, without conducting any experiments.

Front

How do you calculate the probability of a single event?

Back

The probability of a single event is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.

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

Back

The probability of rolling an even number (2, 4, or 6) is 3/6 or 1/2.

In a jar with 2 pink, 6 red, and 4 blue marbles, what is the probability of picking a red marble?

Back

The probability of picking a red marble is 6/12 or 1/2.

Front

What is the probability of rolling a number greater than 4 on a die?

Back

The probability of rolling a number greater than 4 (5 or 6) is 2/6 or 1/3.
