Say there are 4 stations for ice cream toppings.
station1: 3 choices
station2: 2 choices
station3: 2 choices
station4: 3 choices
How many different combinations toppings can I get assuming I pick 1 topping from each station?
Would it be 3 * 2 * 2 * 3 = 36
Yes, assuming the combinations don't need to be distinct (or no 2 stations serve the same choice).
Personally, I prefer distinct ice cream toppings on my ice cream.
