Given are n boxes, each containing n−1 balls. Specifically, the i-th box contains i−1 white balls and n−i black balls (i=1,2,…,n). A box is randomly selected, and then two balls are drawn from it without replacement. (a) Determine the probability that the first drawn ball is black. (b) Determine the probability that the second drawn ball is black. (c) Determine the probability that the second drawn ball is black, given that the first ball drawn was black.
