Simple, Theoretical, and Experimental Probability

What is a theoretical probability?

• The probability calculated based on the possible outcomes in a perfect scenario.

• The probability based on historical data and past events.

• The probability that is always equal to 1.

• The probability that can only be determined through experiments.

What does 'more likely' mean in probability?

• It means the event will definitely occur.

• It means the probability of the event is exactly 0.5.

• It means the probability of an event occurring is greater than 0.5.

• It means the event is impossible.

What is probability?

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

• A method to predict future events based on past occurrences.

• A statistical tool used to analyze data sets.

• A way to ensure that events will happen with certainty.

What is an experimental probability?

• It is the probability calculated based on theoretical models.

• It is the probability determined by conducting experiments and observing the outcomes.

• It is the probability that is always equal to 1.

• It is the probability that cannot be measured.

What does it mean if an event is 'impossible'?

• An event is 'impossible' if it cannot happen at all, with a probability of 0.

• An event is 'impossible' if it is very unlikely to happen, with a probability close to 0.

• An event is 'impossible' if it can happen but is highly improbable.

• An event is 'impossible' if it happens frequently, with a probability of 1.

How do you calculate the probability of a single event?

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

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

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

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

What does it mean if an event is 'certain'?

• An event is 'certain' if it is guaranteed to happen, with a probability of 1.

• An event is 'certain' if it is likely to happen, with a probability of 0.5.

• An event is 'certain' if it is impossible to happen, with a probability of 0.

• An event is 'certain' if it may or may not happen, with a probability of 0.75.

What does 'less likely' mean in probability?

• It means the event is certain to happen.

• It means the probability of an event occurring is less than 0.5.

• It means the event is impossible to happen.

• It means the event is equally likely to happen or not.
