#### Explanation:

Apart from the wordy explanation, what you have is a set of data. It is in Table form to define some categories. Two flavors and two age groups are made. We could do similar analyses on any of the age groups or flavors. In all cases, what they are calling "frequency" is just the number of times something occurs. What they call a "marginal frequency" (unnecessary definition) is just the percentage of one category to another.

In this case chocolate is the only criterion, so the age groups don't matter. The percentage of ALL respondents who prefer chocolate to vanilla is as indicated,

IF we wanted to know only how many TEENS preferred chocolate we would use the value for chocolate in the teens column:

Teens preferring chocolate (amongst teens only)

Adults preferring chocolate (amongst adults only)

That would seem to indicate that adults prefer chocolate more than teens!
