Problem 4. Optional. (10 Bonus Points) Alice, Bob, Charlie, David, and Eve are friends trying to decide whether to go skiing or study next weekend. Each casts a vote. Let their votes be denoted by predicates a, b, c, d, and e where each is True if the preference is for skiing, and False if the preference is for studying. Write a python formula (using and, or, not, and parentheses - no "if" statements or other Python operators allowed) that is True if the majority wants to ski, and False if the majority wants to study. Note that you can break long lines in Python with a backslash
