Question 221683: Your favorite pizza parlor offers six meat toppings and eight veggie toppings. If you order a three-topping pizza at random, what is the probability that it is vegetarian?
14 toppings offered, so n = 14
Arrange in groups of 3, so r = 3
n!/r!(n-r)!
14!/3!(14-3)! = 364 possible combinations
