What is Simple Probability?

Back

Simple Probability is the measure of the likelihood that a specific event will occur, expressed as a ratio of favorable outcomes to the total number of possible outcomes.

Front

What is the formula for calculating probability?

Back

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

Front

What is an example of an impossible event in probability?

Back

Rolling a 15 with a pair of dice is impossible because the maximum sum of two dice is 12.

Front

What is Experimental Probability?

Back

Experimental Probability is the probability based on the actual results of an experiment, calculated as the number of times an event occurs divided by the total number of trials.

Front

What is Theoretical Probability?

Back

Theoretical Probability is the probability based on the expected outcomes in a perfect scenario, calculated as the number of favorable outcomes divided by the total number of possible outcomes.

If a spinner has 12 equal sections, and 5 are red, what is the probability of spinning red?

Back

The probability of spinning red is 5/12.

What is the probability of choosing a letter other than 'A' from the word 'ALGEBRA'?

Back

The probability of choosing a letter other than 'A' is 5/7.

Front

What does it mean if an event is 'equally likely'?

Back

An event is 'equally likely' if it has the same chance of occurring as not occurring.

Front

What is a sample space in probability?

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.
