A dumb bar bet...
 

Hey all

I was hoping for some assistance from the statisticians to settle a dumb bar bet. I run a bar that carries 93 different liquors and cordials and 12 non-alcoholic mixers. We were debating how many drinks we could actually create (some of them being completely undrinkable not withstanding) assuming no drink would have more than 5 alcoholic and 3 non-alcoholic ingredients. Any way I can do this math?

My Thanks

93C5 * 12C3, no?

I don't have a calculator on me so I don't know the answer or if that's the actual equation to use. I'm likely way off.

correct equation or not, that's the best avatar in the world...

well before jumping into combinations lets think about it.

each alcoholic beverage can be mixed w/ either 1,2,or upt eo 3 mixers. so we have 93*3 immediately for the 1 alcoholic drink + all possible mixers.

now, for 2 alcoholic drinks we do 93C2 for the total # of 2 combinations out of 93 objects. so there's 4278 different ways to mix 2 alcoholic drinks. again we take this # and *3 to get the total # of 2 alcoholic drink mixes.

now for 3,4,5 its the same thing, ...

Total= 93C1*3 + 93C2*3 + 93C3*3 + 93C4*3 + 93C5*3=

165,075,465

so there you have it over 165 million different drinks.

unless i made a mistake which i may have.

My answer is 16,123,871,372,127 drinks

94*94*94*94*94 7,339,040,224
x 13*13*13 2,197
= 16,123,871,372,128
- 1 (because a drink with no alcohol and no mixer isnt a drink)

Assumptions: 7-up with no alchohol is OK
Scotch with no mixer is OK
Double scotch with no mixer is not the above.

That's what I was thinking at first, but I have to figure on the different combinations of mixers too and I don't know the equation. I think it's more than 165 million because I have to figure on each combo of liquor with every combo of mixer. So vodka cranberry + vodka oj + vodka cranberry oj + vodka soda + vodka cran soda + vodka cran OJ soda...... and I can't figure in all the various combinations. I think it should come out to billions of possibilities....

Sorry, didn't see you weren't yet jumping into different combinations...

Re: A dumb bar bet...
 

So the formula is that simple? The number of liquors to the power of however many times I can use them * etc. etc.? somehow I thought it would be more difficult, but then again I'm not much of a statistician.

Many Thanks,

Re: A dumb bar bet...
 

That's the answer for drinks with exactly 5 liquors and 3 mixers. The OP asked for all drinks, which includes those with just 3 liquors and 2 mixers, etc. So the real answer is:

93C5*12C3 + 93C4*12C3 + 93C3*12C3 + 93C2*12C3 + 93C1*12C3 + 93C5*12C2 + 93C4*12C2 + 93C3*12C2 + 93C2*12C2 + 93C1*12C2 + 93C5*12C1 + 93C4*12C1 + 93C3*12C1 + 93C2*12C1 + 93C1*12C1 + 93C5*12C0 + 93C4*12C0 + 93C3*12C0 + 93C2*12C0
= 16452521345

Edit: I'm not counting any drink without alcohol as a drink.
