The probabilities that a student passes in Mathematics,Physics and Chemistry are m, p and c, respectively. Of these subjects, the student has a 75% chance of passing in at least one, a 50% chance of passing in at least two and a 40% chance of passing in exactly two. Which of the following relations are true?

The probability that a candidate selected in competitive examinations of B.S.F., C.D.S., Bank P.O. and a, b and c respectively. Of these examinations, a candidate has 70% chance of selection in at least one, 50% chance of selection in at least two and 30% chance of selection in exactly two examinations. If a+b+c=I/m , then find l+m if LCM (m)=1 .

Out of 100 students, 55 passed in Mathematics and 67 passed in Physics 100 students passed at least one of these two subjects. Find how many students passed in Physics only?

The probability that a student will pass in Mathematics is 3/5 and the probability that he will pass in English is 1/3. If the probability that he will pass in both Mathematics and English is 1/8, what is the probability that he will pass in at least one subject?

The probability that a student passes in a physics test is 2/3 and the probability that he passes both the physics and English test is 14/45 . If the probability that he passes at least one test is 4/5 , find the probability that the student passes exactly one of the two tests

The probability that a candidate passes in physics is 70% and that the passes in chemistry is 40% . What is the probability that the candidate passes in any one of the two subjects ?
