magine you are the owner of a pizza shop that offers three different types of crusts, seven different toppings, and three different cheeses. Create an advertisement for your shop listing all the choices you offer and advertising a three-topping pizza with one type of cheese for $9.99 How many different combinations of 1 crust, 3 different toppings, and 1 cheese does your shop offer? Of the possible combinations you offer, which is your favorite? What is the probability that a person would order your favorite pizza at random?
I would imagine being very overweight....:-)
No. of different combinations= \[3C1 \times 7C3 \times 3C1\] (no. of ways of choosing 1 out of 3 crusts * ways of choosing 3 out of 7 toppings * ways of choosing 1 out of 3 cheeses) Now there can only be 1 combination that is ur favourite...so wat is the probability that someone would order that?
