Question

college needs additional faculty members  one for math, two for chemists, and 1 for engineering. HOw many ways can these positions be filled if there are 2 applicants for math, 6 for chemistry, and 3 for engineering?

Well for this all you do is ...

two math applicants Choose 1 
Six chemistry applicants choose 2
Three engineering applicants choose 1

Looks like this

(2C1) x (6C2) x (3C1) = 90

I think this is the answer.

Look for the Choose function on your calculator
