After the final examination, it is found that 3 of the first year, 10 of the second year, and 5 of the third year performed excellent and got a grade of 1.00 for the subject. If a student is chosen at random from this class and is found to have earned an A, what is the probability that he or she is a second year student? (Round your answers to two decimal places)
