Really?

anonymous · Answer

It's that simple?

shane_b · Answer

Yes...since she can only pick one of each and the order of her choices doesn't matter.

anonymous · Answer

oh ok.. Do you have time for one more?

shane_b · Answer

I do...but prob & stats isn't my thing.  This was just an easy one :)

anonymous · Answer

its kinda the same type of question.
A restaurant offers four sizes of pizza, two types of crust, and eight toppings. How many possible combinations of pizza with one topping are there?

shane_b · Answer

Same thing...since she's only picking one of each item and again, the order doesn't matter.  You may also see it calculated as a product of ratios:$$\frac{1}{4}*\frac{1}{2}*\frac{1}{8}=\frac{1}{64}$$So there are 64 difference combinations available.
