Question 352458: A hamburger place has 25 different toppings. You can have a hamburger with upto 5 different toppings. Assume no toppings are used more than once, how many different choices are available? I did this by 25x24x23x22x21= 6,375,600 Did I do this right?
Answer by jim_thompson5910(35256)   (Show Source):
You can put this solution on YOUR website! If the order of the toppings matters, then you are correct. However, I don't think the order matters (the book might say otherwise). If this is the case, then you need to divide by  to get 
So if order doesn't matter, then there are 53,130 different combinations.
