combinations

I have a little Mexican restaurant.  We offer a make-your-own menu.  I would like to know how many possible combinations exist. 
We are building a burrito
First step, Column A-Choose one out of six meat options
Second, Column B-Choose between Rice Only, Beans Only, Rice & Beans together, or none at all (Four choices)
Third, Column C-Choose between 15 diferrent veggies, cheese, and extras.  You can choose all of them, some of them, or none of them
Fourth, Column D-Choose one out of seven salsas.

Can anyone help me with this number?
Thank you.  Whoever helps me gets some free burritos and beverages.

Re: combinations

First multiply the number of options available in steps 1, 2, and 4.  This gives you 6 meat options X 4 rice/bean options X 8 salsa options (assuming you can choose no salsa) = 192.

Now you need to determine the number of ways of choosing options in step 3.  This looks like



Multiply those together and you get a total of 192 X 32768 = 6,291,456 possible combinations.

Re: combinations

It looks like it all depends on whether you can choose no salsa or not.

Hi CEHolcomb;

I am very hungry! Welcome to the forum!


In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.

Re: combinations

Hi CEHolcomb!

All three answers are Humongous!  You might consider hiring someone to counsel your customers
or offer a course in "menu choices."   Does it take the customers quite a while to make all of these
choices?  It might take a while to go through millions of possibilities (ha ha)!

Have a "choice" day!  smile

You are right stefy!  I think I pulled in a "dyslexia" moment.  Humongous anyway, eh?  smile

Yes, that five was on the bottom. I typed out the LaTeX wrong.

Then there's nothing to discuss. We wait to see if the OP has any questions.
