Twelve people from a club, by picking lots. One of them will host a dinner for all once in a month. The number of dinners a particular member has to host in one year is________?
Correct answer: D. Cannot be determined
- A. One
- B. Zero
- C. Three
- D. Cannot be determined
Explanation
Picking one host from 12 people each month does not guarantee a fixed number of selections for any particular member, because the lots are random. A member could host 0, 1 or several dinners in 12 months, so the number cannot be determined; the likely mistake is choosing one by dividing 12 months equally among 12 people.
