Investigate!
A recent buzz marketing campaign for Village Inn surveyed patrons on their pie preferences. People were asked whether they enjoyed (A) Apple, (B) Blueberry or (C) Cherry pie (respondents answered yes or no to each type of pie, and could say yes to more than one type). The following table shows the results of the survey.
| Pies enjoyed: | A | B | C | AB | AC | BC | ABC |
| Number of people: | 20 | 13 | 26 | 9 | 15 | 7 | 5 |
How many of those asked enjoy at least one of the kinds of pie? Also, explain why the answer is not 95.
