Question
Be sure to show your formulas/calculations for these questions:
(a) In ENGR 270, there are 6 lab groups, and 9 lab boxes (numbered
"1" through "9") available. Assuming each lab group will be as-
signed one box, how many different ways can these assignments
be made?
(b) When registering for classes, you are required to take:
one science course;
one math course; and
either a humanities course or a social science course.
Assuming there are 4 science courses; 8 math courses; 2 humanities
courses; and 2 social science courses to choose from, how many
different schedules are possible?
(c) On an exam, there are 12 questions, and you are asked to answer
10. How many different ways can you choose 10 questions out of
12?
