What is probability?

Back

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

Front

What is the formula for calculating the probability of an event?

Back

The probability of an event is calculated as the number of favorable outcomes divided by the total number of possible outcomes.

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 the probability of an event that cannot happen?

Back

The probability of an event that cannot happen is 0.

Front

What is the probability of an event that is certain to happen?

Back

The probability of an event that is certain to happen is 1.

Front

How do you calculate the probability of multiple independent events occurring?

Back

To calculate the probability of multiple independent events occurring, multiply the probabilities of each individual event.

Front

What is a tree diagram in probability?

Back

A tree diagram is a visual representation of all possible outcomes of a probability experiment, showing the paths to each outcome.

Front

What is theoretical probability?

Back

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

Front

How do you find the probability of selecting a specific item from a group?

Back

To find the probability of selecting a specific item, divide the number of that item by the total number of items in the group.

Front

What is the complement of an event in probability?

Back

The complement of an event is the set of outcomes in the sample space that are not included in the event.
