fill in the missing values in the table below.

book preference

	print	electronic	total
adults
total

Explanation:

Step1: Calculate the total number of youths

The number of youths who prefer print books is \(38\), and the number of youths who prefer electronic books is \(26\).
So the total number of youths is \(38 + 26=64\).

Step2: Calculate the number of adults who prefer electronic books

The total number of people surveyed is \(120\). The total number of youths is \(64\), so the number of adults is \(120 - 64 = 56\).
The number of adults who prefer print books is \(21\), so the number of adults who prefer electronic books is \(56-21 = 35\).

Step3: Calculate the total number of print - book lovers and electronic - book lovers

The total number of print - book lovers is \(38+21 = 59\).
The total number of electronic - book lovers is \(26 + 35=61\).

Answer:

	Print	Electronic	Total
Adults	\(21\)	\(35\)	\(56\)
Total	\(59\)	\(61\)	\(120\)
