A pizza place advertises that they have 2 types of crust (round, square) and 5 toppings (pepperoni, sausage, bacon, green peppers, mushrooms). You call and order a pizza with 1 topping and tell the pizza maker to surprise you. What is the probability you are made a round pizza with bacon? Leave as a fraction. Determine whether a combination or permutation should be used to find the number of possibilities. There are 6 runners competing in a race. How many ways can 1st, 2nd, and 3rd place occur?
