There are 3 bags each containing 5 white and 3 black balls. Also there are two bags each contains 2 white and 4 black balls. A white ball is drawn at random. Find the probability at the event that white ball is from a bag of the first group.

Each of the n urns contains 4 white and 6 black balls. The (n+1) th urn contains 5 white and 5 black balls. One of the n+1 urns is chosen at random and two balls are drawn from it without replacement. Both the balls turn out to be black. If the probability that the (n+1) th urn was chosen to draw the balls is 1/16, then find the value of n .
