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

OpenStudy (misssunshinexxoxo):

Which do you believe it is?

OpenStudy (anonymous):

1000?

OpenStudy (misssunshinexxoxo):

" chosen other than the one he selected?"

OpenStudy (misssunshinexxoxo):

10 times 10 times 10; says he already has an option

OpenStudy (anonymous):

so no?

OpenStudy (misssunshinexxoxo):

Chances are based on this we subtract one since he already had it

OpenStudy (anonymous):

so 999 right

OpenStudy (misssunshinexxoxo):

Correct :)

OpenStudy (anonymous):

thanks!

OpenStudy (misssunshinexxoxo):

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.

OpenStudy (misssunshinexxoxo):

Do you agree?

OpenStudy (anonymous):

yes i agree

OpenStudy (anonymous):

yeah I actually helped someone with this earlier. It's an awfully worded question

OpenStudy (anonymous):

OpenStudy (anonymous):
