Joan and Jim would like to know how many different dinner menus they have to choose from. One way to make sure you have considered the entire sample space – all the possible menu outcomes – is to make a table like the one at right. How many different menus are there?
Each line represents one unique dinner menu.

What is the probability they pick a menu without meat? What is the probability they pick a menu with chocolate?
