Probability and Two Way Frequency Tables

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, or as a percentage.

Front

What is a two-way frequency table?

Back

A two-way frequency table is a table that displays the frequency of different outcomes in two categorical variables.

Front

How do you calculate the percentage of an event?

Back

To calculate the percentage, divide the number of favorable outcomes by the total number of outcomes and multiply by 100.

Front

What does it mean if an event has a probability of 0?

Back

An event with a probability of 0 means that it is impossible for that event to occur.

Front

What does it mean if an event has a probability of 1?

Back

An event with a probability of 1 means that it is certain to occur.

Front

How can you interpret a two-way frequency table?

Back

You can interpret a two-way frequency table by analyzing the counts of occurrences for each combination of the two variables.

Front

What is the formula for finding the probability of an event?

Back

The formula is: Probability = (Number of favorable outcomes) / (Total number of outcomes).

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 the difference between theoretical and experimental probability?

Back

Theoretical probability is based on the expected outcomes, while experimental probability is based on actual experiments and observations.

Front

How do you find the least popular option in a frequency table?

Back

To find the least popular option, look for the lowest frequency count in the table.
