To decide what to eat at a restaurant, Frank closes his eyes, places his finger on the menu, and orders whichever dish he places his finger on. He chooses one salad, one main course, and a dessert. If there were 10 possible dishes for each selection, how many possible combinations could he have chosen other than the one he selected?
99
100
999
1,000

I just would like to note with @peachpi since he is seeing this; we need to change the way they word questions because most would pick 1,000 and the truth it's 999.
