A bag contains 4 white and 3 black balls. Two balls are drawn at random one after another with replacement. What is the probability that the first draw will give a black hall and the second draw will give a white ball?
Two balls are drawn one by one at random without replacement. The probability that the second drawn ball is white. Therefore, the probability that the second drawn ball is white = (2/7) + (2/7) = 4/7.
