Question: Question 9: There are three universities in a town producing MBA graduates. University A produces 50% graduates, university B 30 % and university C 20 % graduates. Assume that 40 % graduates of university A, 50 % graduates from university B and 60 % graduates from university C get a job within 3 months of graduating. If a graduate has just been employed within 3 months of his graduation, what is the probability that he graduated from university A?
