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.

About Sequences and Series

Sequences describe ordered terms formed by a pattern, while series represent the sum of those terms. Questions cover arithmetic and geometric sequences, their nth terms, common difference or ratio, finite sums, and applications, with the sequence itself kept distinct from the corresponding series.
