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.

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.

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

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!

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

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