How can a coin flip be used in probability?

Back

A coin flip can represent a binary outcome (e.g., heads or tails), making it useful for experiments with two possible results.

What does it mean for outcomes to be equally likely?

Back

Outcomes are equally likely when each outcome has the same chance of occurring in a probability experiment.

How can rolling a die simulate random selection?

Back

Rolling a die can simulate random selection by assigning each face of the die to a different outcome, allowing for equal probability of each outcome.

What is the significance of using a number cube in probability experiments?

Back

A number cube (die) can represent multiple outcomes and is often used to simulate random events with a finite number of possibilities.

What is a sample space in probability?

Back

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

Front

How do you calculate the probability of an event?

Back

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

What is a random experiment?

Back

A random experiment is a process or action that leads to one or more outcomes that cannot be predicted with certainty.

What is the difference between theoretical and experimental probability?

Back

Theoretical probability is based on the expected outcomes of an event, while experimental probability is based on the actual results of an experiment.
