Combinations of Burrito toppings: how many ways to order

[Jaskaran]

Combination problem! Easy?

At a Chipotle Restaurant. How many ways can you order a single menu item from a Chipotle Restaurant? (For example, to order a burrito you must make the following choices:
• Rice or no rice,
• Pinto beans, vegetarian black beans, or no beans,
• Braised carnitas, barbacoa, adobo marinated and grilled chicken, beef, or no meat,
• Guacamole or not,
• Salsa or not,
• Cheese or not,
• Sour cream or not.

Hmmmm, I don't understand that if this is a general type of problem or that I have to compute the combinations for each. If so, what would I use? Combinations or permutations? HOw would I justify the solution to this problem?

These are all independant events - that is choice of beans (or "no beans") does not affect choice of cheese (or "no cheese").

So just multiply the number of choices.
