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? (a) `p+m+c=19/20` (b) ` p+m+c=27/20` (c) `p m c=1/10` (d) `p m c=1/4`
