Q. 10 The probabilities that a student passes in Mathematics, Physics and Chemistry are m, p and c respectively. Of these subjects, the student has 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. Following relations are drawn in m, p and c:
1. p + m + c = 27/20 2. p + m + c = 13/20 3. (p) × (m) × (c) = 1/10
(A) Only relation 1 is true
(B) Only relation 2 is true
(C) Relations 2 and 3 are true
(D) Relations 1 and 3 are true
Answer: (D)
