Final answer:
The information provided does not specify details relevant to the student's question regarding professional athletes' ownership of certain items, thus we cannot calculate the various numbers of owners for the given items.
Step-by-step explanation:
The student's question cannot be answered accurately as the given information pertains to different survey examples and does not provide specific data regarding the professional athletes and their ownership of the items mentioned (convertible, giant screen TV, sporting goods store). To solve the question, data such as the total number of athletes owning each item individually, the number of athletes owning combinations of these items, or the number of athletes not owning any would be required. Without this specific information, we are unable to calculate the number of athletes that did not own any of the three items, those who owned a convertible and a TV but not a store, those who owned a convertible or a TV, those who owned exactly one type of item, those who owned at least one type of item, and those who owned a TV or store but not a convertible.
