Problem 8. Suppose I have 50 strings. At every step, I randomly pick 2 ends of strings (they could be the ends of the same string) and tie them together. At each step, I could make either a longer string or a loop. a) What is the expected number of steps it takes me to turn all the strings into loops? b) What is the expected number of loops? (Express this as a sum)
