A certain brand of cereal comes with a good guy action figure and a bad guy action figure in its box. Each action figure comes in a variety of different colors (but they all have the same color options), and whichever action figures you get will match in color. There are seven possible good guy action figures and four possible bad guy action figures. An advertisement for this cereal claims that there are over 200 different options for the good guy, bad guy, and color combinations that you could end up with. What are the fewest number of color options they must have in order for this to be true? PLEASE DO A SLOT DIAGRAM
There are 7*4 = 28 different pairs of figures you could get
so, you will need 8 colors to make sure there are 200 unique pair/color combinations
