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 False if the majority wants to ski, and True if the majority wants to study. Note that you can break long lines in Python with a backslash.

Assume the existence of a bankaccount class. define a derived class, savingsaccount that contains two instance variables: the first a double, named interestrate, and the second an integer named interesttype. the value of the interesttype variable can be 1 for simple interest and 2 for compound interest. there is also a constructor that accepts two parameters: a double that is used to initialize the interestrate variable, and a string that you may assume will contain either "simple", or "compound", and which should be used to initialize the interesttype variable appropriately. there should also be a pair of functions getinterestrate and getinteresttype that return the values of the corresponding data members (as double and int respectively).
