Best ResponseYou've already chosen the best response.2It is given that  Equal num study all three subjects as those who learn none of the three. The people who do not study any of them are given by U  (A U B) Here, U = 63 .. And, A U B is given be (a+b+c+d+e) and, I considered the people who study all the three as 'e' And, Sorry, I did a mistake .. I would be > e = 63  (a+b+c+d+e)
