In a school there are 3 sections A, B and C. Section A contains 20 girls and 30 boys, section B contains 40 girls and 20 boys and section C contains 10 girls and 30 boys. The probabilities of selecting the section A , B and C are 0.2,0.3 and 0.5 respectivley. If a student selected at random from the school is a girl, then the probability that she belongs to section A is
