If he must take at least 1 of his 3 electives from each group, how many choices does he have?(Hint: First find how many choices he has if he elects only 1 course from group I. Then find how many choices he has if he elects 2 courses from group I. Since he must do one or the other of these, the final answer is the sum of the two answers.)\r
