In Exercises 59 - 62, recall that in Section 1.1 we introduced the following arrangement of numbers, which is called Pascal’s triangle. Notice that the fourth line* of this triangle contains the numbers 1 , 4 , 6 , 4 , 1 , which, as we saw in Example 5 are precisely the counts of the number of the subsets of a four-element set with 0 , 1 , 2 , 3 , and 4 elements respectively. *We start counting these lines with 0 , not 1 . With this observation in mind, how do you interpret the fifth line of Pascal’s triangle?
