A bag contains `n` balls, one of which is white. The probability that `Aa n dB` speak truth are `P_1a n dP_2,` respectivley. One ball is drawn from the bag and `Aa n dB` both assert that it is white. Find the probability that drawn ball is actually white.

A bag contain n ball out of which some balls are white.If probability that a bag contains exactly i white ball is prooportional to i^(3).A ball is drawn at random from the bag and found to be white,then find the probability that bag contains exactly 2 white balls.
