Basic Probability

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 theoretical probability of an event?

Back

Theoretical probability is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.

Front

What is experimental probability?

Back

Experimental probability is calculated based on the results of an experiment, found by dividing the number of times an event occurs by the total number of trials.

Front

If a cube has 6 faces, what is the probability of rolling a specific number?

Back

The probability of rolling a specific number on a fair 6-sided die is 1/6.

Front

What is the formula for calculating probability?

Back

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

Front

What does it mean if the probability of an event is 0?

Back

If the probability of an event is 0, it means that the event cannot occur.

Front

What does it mean if the probability of an event is 1?

Back

If the probability of an event is 1, it means that the event is certain to occur.

Front

How do you find the relative frequency of an event?

Back

Relative frequency is found by dividing the number of times an event occurs by the total number of trials.

Front

What is the probability of not rolling a six on a fair die?

Back

The probability of not rolling a six is 5/6.

Front

What is a sample space in probability?

Back

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