3. The store at your school wants to stock sweatshirts that come in four sizes (small, medium, large, xlarge) and in two colors (red and white). How many different types of sweatshirts
will the store have to stock?

The different types of sweatshirts that store have to stock can be calculated as 4×2=8 sweatshirts. Another approach to calculate the different type of sweatshirts that store have to restock is by making the sample space. Let S denotes small, M denotes medium, large denotes L, extra large denotes EL, R denotes red and W denotes white. S={ SR,MR,LR,ELR,SW,MW,LW,ELW}.

The total element in the sample space are 8. So, there are 8 different types sweatshirts that store have to stock.
