A shop has available toppings of anchovies, bacon, pepperoni, peppers, sausage, olives, and onionsHow many different ways can a be made with 3 toppings?
There are a total of 7 toppings available, and we need to choose 3 toppings to put on the pizza. This is a combination problem, so we can use the formula for combination to calculate the number of ways:
Number of ways = nCr = n! / r!(n-r)!
Number of ways = 7C3 = 7! / 3!(7-3)! = 35
Therefore, there are 35 different ways to make a pizza with 3 toppings from the available options.
