In a class of 60 students 41 are taking French, 22 are taking German. Of the students taking French or German, 9 are taking both courses. How many students are not enrolled in either course?	Choose the most appropriate option:	A) 6	B) 15	C) 24	D) 33	E) 54
Formula for calculating two overlapping sets:   6 + B - both + NOT(6 or B) = Total   so in our task we have equation:   41 (french) + 22 (german) - 9 (both) + NOT = 60   54 + NOT = 60   NOT = 60 - 54=
