Problem
Your class is given the option of choosing a day for the final exam. The students in the class are asked to rank the three available days, Monday $(M)$, Wednesday $(W)$, and Friday (F). The results of the election are shown in the following preference table. Complete parts (a) through (d) below. \begin{tabular}{|l|c|c|c|c|} \hline Number of Votes & 15 & 9 & 3 & 2 \\ \hline First Choice & F & F & W & M \\ \hline Second Choice & W & M & F & W \\ \hline Third Choice & M & W & M & F \\ \hline \end{tabular} c. How many students selected Monday as their first choice for the final? student(s) (Type a whole number.) d. How many students selected Friday as their first choice for the final? student(s) (Type a whole number.)
Solution
Step 1 ：From the preference table, we can see that 2 students selected Monday as their first choice for the final exam. So, the number of students who selected Monday as their first choice for the final is \(\boxed{2}\).
Step 2 ：Similarly, from the preference table, we can see that 15 students and 9 students selected Friday as their first choice for the final exam. So, the total number of students who selected Friday as their first choice for the final is \(15 + 9 = \boxed{24}\).
