A student has to choose one club from (3) clubs and one sport from (4) sports. If the student also chooses one shift from (2) shifts how many ways are possible?

Answer and explanation

Correct answer: 24

Choosing a club, a sport, and a shift are three independent choices. For each club, there are 4 sport choices, and for each sport, there are 2 shift choices. Therefore, by the fundamental principle of counting, the total number of ways is \(3 \times 4 \times 2=24\). The value \(12\) counts only the club and sport choices and misses the shift choice. Exam tip: Multiply the number of choices when all selections are made together.
