Best ResponseYou've already chosen the best response.0Hmm. We have three courses of meal, lets call them A, B and C. And we have three types of vegetable lets call them a,b and c. Aa denotes that, "meal A and vegable a" Ab denotes that, "meal A and vegetable b" Ac denotes that, "meal A and vegetable c" Ac, Aa and Ab are three of those meal combinations. We have three vegetable for each of those course, so the total combinations, is 9. \[3 \times 3 = 9\] (number of courses) times (number of vegetables)
