1) Let Pn denote the number of ways to build a pipe n units long, using segments that are either plastic or metal, and (for each material) come in lengths of 1 unit or 2 units. For example, p1 = 2 since we can use a 1-unit segment that is either plastic or metal, and p2= 6 since we can use either type of 2-unit segment, or any of the 22 possible ordered choices of 2 segments each having a length of 1 unit. Define po = 1. Determine a recurrence relation for pn. Give a combinatorial proof that your recurrence relation does solve this counting problem. Use your recurrence relation and the method of generating functions to find a formula for pn. [Hint: Your final answer should be Pn= 1 2√3 (1+√3)+¹-(1-√3)+¹ for every n 20.] 2) Let s, denote the number of lists of any length that have the fixed sum of n, and whose entries come from {1,2,3). For example, s2 = 2 because (1,1) and (2) are the only such lists; and 84 = 7 because the lists are (3, 1), (1, 3), (2, 2), (2, 1, 1), (1, 2, 1), (1, 1,…
