There are 100 students in a class. In the examination, 50 of them failed in Mathematics, 45 failed in Physics, 40 failed in Biology and 32 failed in exactly two of the three subjects. Only one student passed in all the subjects. Then, the number of students failing in all the three subjects is

The probability of A to fail in an examination is 1/5 and that of B is 3/10 . If the probability that both of them fails is 3/50 , then the probability that only one of A and B fails, is
