Weirdly worded question.

I was thinking that in (2) the answer is the sum of 5C3 + 10C2

Problems worthy of attack prove their worth by hitting back. (Piet Hein)

Anyone working on part 3?

is it not 450 ....5C3*10C2

(3) looks like 2! x 5C3 x 10C2... since 2 ways of selecting salad

no

395 ?

How do you get 395?

395 is wrong and so is 2!*C(5,3)*C(10,2)

do i add them instead of multiply

Is 450 correct?

no

@ Mr. Fool for Math
5C3*10C2 - [5C3 + 10C2]
