Problem

James is doing research on men's facial hair. To do so, he takes families with 4 men and categorizes each man as having no facial hair, some stubble, or a beard.
His results are shown in the table below. "N" represents a man with no facial hair, "S" represents a man with stubble, and "B" represents a bearded man.
Drag the bars to make a relative frequency plot that shows the proportion for each possible number of men with stubble in a group.
