Answer: No, I wouldn't because he didn't do what he was told.

Step-by-step explanation: Using Matt's survey we draw a Venn Diagram.

Venn Diagram is a diagram used to show the logical relationship between two or more set of items.

The survey Matt did is represented below.

To construct the diagram:

1) Create 3 sets of data (represented by the circles) intersecting each other;

2) The space where the three intersect is the number of people surveyed that preferred all types. So, we write 7 in the space;

3) According to the research, 19 preferred comedies and variety. But there are already 7 in the intersect, so, 12 has those preferences;

4) Following the same logic, 14 preferred variety and drama. Then, 7 has those preferences;

5) And, 8 preferred comedy and drama;

6) Now, to determine how many of them has an exclusive preference, we take the data and subtract the already known values:

7) 5 don't like any of the types, so it is represented outside the three circles;

After creating the Diagram, we can determine how many people answered the poll:

total = 31 + 12 + 12 + 8 + 7 + 7 + 22 + 5

total = 104

Therefore, as a personnel manager, I wouldn't hire Mr. Matic because he was supposed to poll 100 people but he polled 104 people.
