Simple example

A person has decided to shop at one store today, either in the north part of town or the south part of town. If they visit the north part of town, they will shop at either a mall, a furniture store, or a jewelry store (3 ways). If they visit the south part of town then they will shop at either a clothing store or a shoe store (2 ways).

Thus there are 3 + 2 = 5 {\displaystyle 3+2=5} possible shops the person could end up shopping at today.
