PLEASE HELP!! True or False & Explain Please!: If a pizzeria offers 5 different toppings to put on their pizzas (assume it also prepares pizzas with no toppings), then it offers a total of 25 pizzas with at least 2 toppings.
no. If you mean only two different toppings then you have 10 combinations. 5*4/2 because pepperoni and tomato is the same as tomato and pepperoni but with three toppings you have 5 * 4 * 3 /6 choices and with 4 toppings you have 5 * 4 * 3 * 2 / 24 choices (5 choices since you can leave off one of 5 toppings) and with 5 toppings you have 1 choice
