Easy one, but i liked the language :wink: imagine vodka and whiskey with orange and lime juice ... i remember my college days

There are five possible non-alcoholic ingredients: cranberry juice, orange juice, pineapple juice, limejuice, or lemon juice. If the bar uses two alcoholic ingredients and two non-alcoholic ingredients, how many different drinks are possible?

A. 100
B. 25
C. 50
D. 75

What if we change it up by adding the following:

"The owner is a peculiar little !@#$and claims he can tell when one ingredient is added before another. With the same number of ingredients above, 2 non-alcoholic and 2 alcoholic drinks of the 5 of each, how many different flavors are possible?" _________________ ------------------------------------ J Allen Morris **I'm pretty sure I'm right, but then again, I'm just a guy with his head up his a$\$.

What does the "C" stand for here?

5(# of alcohol) C(??) 2(since we mix 2 drinks) * 5(# of n/a drink) C(??) 2(since we mix 2 drinks)

Am i understanding that part correctly?

droopy57 : you may want to brush up your permutation and combination, please see this.
http://www.mansw.nsw.edu.au/members/ref ... no4yen.htm

in this question C is the formula for number of combinations of taking r things out of n things = nCr = n!/(r! * (n-r)!)
5C2 = 5!/3!*2! = 5*4*3!/2*1*3! = 20/2 = 10
