Question

How many ways can this be done?

Answer 1

140 ways

Explanation:

"Choose 3 appetizers out of 4" can be written in equation as: C(4,3), and that is 4!/[3!(4-3)!]=4 ways.

For main dishes, C(10,9)= 10!/9!(10-9)!=10 ways.

And for desserts, C(9,5)= 9!/[5!(9-5)!]=126 ways.

So ways in total are 4+10+126=140 ways to pick the meals.
