Understanding Probability Concepts Quiz

What is the definition of probability?

• The likelihood or chance of an event occurring.

• The total number of possible outcomes.

• The number of times an event occurs.

What is experimental probability?

• The probability based on the number of favorable outcomes divided by the total number of possible outcomes.

• The probability calculated by conducting an experiment and recording the outcomes.

• The probability of a single event occurring.

What is theoretical probability?

• The probability based on reasoning and calculations without conducting an experiment.

• The probability based on the number of times an event occurs.

• The probability of multiple events occurring together.

What does frequency refer to in probability?

• The number of times an event occurs in an experiment.

• The total number of possible outcomes.

• The likelihood of an event occurring.

What is a sample space in probability?

• The set of all possible outcomes of an experiment.

• The number of times an event occurs.

• The probability of a single event occurring.

What are compound events in probability?

• Events that consist of two or more simple events.

• Events that have only one possible outcome.

• Events that cannot occur at the same time.

What are outcomes in probability?

• The results of a single trial of an experiment.

• The total number of possible events.

• The probability of an event occurring.

How is experimental probability calculated?

• By dividing the number of favorable outcomes by the total number of possible outcomes.

• By dividing the number of times an event occurs by the total number of trials.

• By adding the probabilities of all possible outcomes.

How is theoretical probability calculated?

• By dividing the number of favorable outcomes by the total number of possible outcomes.

• By conducting an experiment and recording the outcomes.

• By multiplying the probabilities of individual events.

What is the probability of an impossible event?

• 1

• 0
