This is a typical set operation problem involving Venn diagrams to analyze different groups based on given conditions. Let's break it down step by step using the provided information.

Given Information:

• Total athletes = 227
• Athletes with a convertible = 99
• Athletes with a giant screen TV = 92
• Athletes with a sporting goods store = 100
• Athletes with a convertible and a store = 14
• Athletes with a TV and a store = 38
• Athletes with a convertible and a TV = 43
• Athletes with all three items = 5

Questions:

1. How many athletes did not own any of the three items?

   We'll calculate the total who own at least one item and subtract from the total number of athletes (227).

2. How many owned a convertible and a TV, but not a store?

   This is the group that owns both a convertible and a TV, but we must exclude those who also own a store. Subtract the athletes who own all three items from the convertible and TV group.

3. How many athletes owned a convertible or a TV?

   This is asking for the union of athletes who own either a convertible, a TV, or both. We will use the formula for union: $|A \cup B| = |A| + |B| - |A \cap B|$

4. How many athletes owned exactly one type of item?

   We must calculate the number of athletes who own only a convertible, only a TV, or only a store. We'll subtract the athletes who own two or more items from the totals for each group.

5. How many athletes owned at least one type of item in the survey?

   This involves calculating the union of the three sets (convertible, TV, and store). Use the inclusion-exclusion principle for three sets: $|A \cup B \cup C| = |A| + |B| + |C| - |A \cap B| - |A \cap C| - |B \cap C| + |A \cap B \cap C|$

6. How many owned a TV or a store, but not a convertible?

   This is the union of the athletes who own a TV or store, minus those who own a convertible.

Let me calculate these and provide the answers.Here are the answers to each of the questions:

1. How many athletes did not own any of the three items?
   Answer: 26 athletes

2. How many owned a convertible and a TV, but not a store?
   Answer: 38 athletes

3. How many athletes owned a convertible or a TV?
   Answer: 148 athletes

4. How many athletes owned exactly one type of item?
   Answer: 116 athletes

5. How many athletes owned at least one type of item in the survey?
   Answer: 201 athletes

6. How many owned a TV or a store, but not a convertible?
   Answer: 102 athletes

Do you need further details or clarifications?

Here are five additional related questions to expand your understanding:

1. How would the results change if 10 more athletes owned all three items?
2. How would the calculation change if no athlete owned exactly two items?
3. Can you create a Venn diagram to visually represent these results?
4. How many athletes owned a convertible and a store but not a TV?
5. What would be the impact if 5 athletes owned none of the items?

Tip: For problems involving overlapping sets, the inclusion-exclusion principle is a powerful tool to calculate unions and intersections of multiple sets.
