Twelve representatives must be picked from a pool of n students who attend a certain class. If m of the students haven’t shown up today, how many different sets of representatives could be picked from the students who came today?

(1) If one less student had shown up, it would be possible to create 13 different sets
(2) n=m+1

On your answer sheet, write down:
a. if statement (1), BY ITSELF is sufficient to answer the question, but statement (2) by itself is not sufficient to answer the question;
b. if statement (2), BY ITSELF is sufficient to answer the question, but statement (1) by itself is not sufficient to answer the question;
c. if statements (1) and (2) TAKEN TOGETHER are sufficient to answer the question, but NEITHER statement BY ITSELF is sufficient to answer the question;
d. if EITHER statement BY ITSELF is sufficient to answer the question; and
e. if statements (1) and (2) TAKEN TOGETHER are NOT sufficient to answer the question.
