Making Predictions with Simple Probability

Front

What is probability?

Back

Probability is a measure of how likely an event is to occur, expressed as a number between 0 and 1, where 0 means the event will not happen and 1 means it will definitely happen.

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.

Front

What is a sample space?

Back

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

Front

What is a favorable outcome?

Back

A favorable outcome is an outcome that satisfies the conditions of the event we are interested in.

If a coin is flipped, what is the probability of getting heads?

Back

The probability of getting heads when flipping a coin is 1/2.

Front

What is the expected value in probability?

Back

The expected value is the average of all possible outcomes, weighted by their probabilities.

Front

How do you make predictions using probability?

Back

You can make predictions by using the ratio of favorable outcomes to total outcomes to estimate how many times an event will occur in a larger sample.

Front

What is a number cube?

Back

A number cube is a six-sided die, with each side showing a different number from 1 to 6.

Front

If you roll a number cube, what is the probability of rolling a 2?

Back

The probability of rolling a 2 on a number cube is 1/6.

What is a spinner in probability?

Back

A spinner is a circular device divided into sections, each representing a different outcome, used to generate random results.
