The probabilities that a student passes in Mathmatics, 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, c:
(I) p + m + c = 27/20
(II) p + m + c = 13/20
(III) (p) * (m) * (c) = 1/10
  • a)
    Only relation I is true
  • b)
    Only relation II is true
  • c)
    Relations II and III are true.
  • d)
    Relations I and III are true.
Correct answer is option 'A'. Can you explain this answer?

Answer should be D.
1-(1-m)(1-p)(1-c) = 0.75
(1-m)pc+m(1-p)c+mp(1-c)+mpc = 0.5
(1-m)pc+m(1-p)c+mp(1-c) = 0.4
Solving these, we get mpc = 0.1,mp+pc+mc = 0.7 and m+p+c=1.35=27/20
