The stock of a warehouse consists of boxes of high, medium and low quality lightbulbs in respective proportions 1:2:2. The probabilities of bulbs of the three types being unsatisfactory are 0-0, 0-1 and 0-2 respectively. If a box is chosen at random and two bulbs in it are tested and found to be satisfactory, what is the probability that it contains bulbs (i) of high quality; (ii) of medium quality; (iii) of low quality?
