Answer

Answer:

The cell labeled a is a joint frequency. The cell labeled b is a marginal frequency.

Brief Explanations:

A joint frequency shows the frequency of data that belongs to two - categories simultaneously. Cell a represents the number of people who have no cell phone and no laptop, so it's a joint frequency. A marginal frequency is the total of a row or a column in a two - way table. Cell b is the total number of people who own a laptop, so it's a marginal frequency.
