i need probability help..7 sandwich options and 9 drink options. how many different ways can you make 3 sandwiches & 2 drinks

OpenStudy (anonymous):

C(7,3)*C(9,2)

OpenStudy (anonymous):

This is assuming that you have to pick 3 different sandwiches and 2 different drinks.

OpenStudy (anonymous):

so what do i multiply though

OpenStudy (anonymous):

If you don't have to pick different stuff, it'd be 7^3*9^2

OpenStudy (anonymous):

so 343 x 81... thats a huge number lol

OpenStudy (anonymous):

Indeed. :)
