Probability Concepts and Calculations

What is experimental probability?

• Experimental probability is the probability determined by conducting an experiment and observing the outcomes.

• Experimental probability is the theoretical probability based on expected outcomes.

• Experimental probability is the probability calculated using historical data.

• Experimental probability is the probability that remains constant regardless of experiments.

What is the formula for calculating probability?

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

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

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

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

What is a compound event in probability?

• A single event that cannot be broken down further.

• An event that involves two or more simple events.

• An event that has no outcomes.

• An event that occurs with certainty.

What is theoretical probability?

• The probability calculated based on the possible outcomes of an event, assuming all outcomes are equally likely.

• The probability based on past events and historical data.

• The probability that is determined by experimental results only.

• The probability that is influenced by personal beliefs and opinions.

What is the probability of not rolling a 3 on a standard die?

• 1/6

• 1/2

• 5/6

• 2/3

What is a favorable outcome?

• An outcome that is always positive

• An outcome that satisfies the conditions of the event for which probability is being calculated

• An outcome that is random and unpredictable

• An outcome that is determined by external factors

What is probability?

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

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

• A statistical tool used to analyze data sets.

• A way to calculate the average of a set of numbers.

What does the Law of Large Numbers state?

• The Law of Large Numbers states that as the number of trials increases, the experimental probability will get closer to the theoretical probability.

• The Law of Large Numbers states that the outcome of a single trial is always predictable.

• The Law of Large Numbers states that all outcomes are equally likely regardless of the number of trials.

• The Law of Large Numbers states that increasing the number of trials will always lead to a higher probability of success.

If a spinner has 8 equal sections, what is the probability of landing on one specific color?

• 1/4

• 1/8

• 1/2

• 1/16

What is a sample space in probability?

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

• A sample space is a collection of events that can occur in a probability experiment.

• A sample space is the average of all outcomes in a probability experiment.

• A sample space is the likelihood of a specific outcome occurring.
