A bag initially contained 4 white marbles and 9 black marbles. A
marble was drawn and replaced by two marbles of the opposite
colour. Then another marble was drawn and also replaced by two
marbles of the opposite colour. A third marble was then drawn. Find
the probability that the first marble drawn was white if:
(a) the third marble drawn was white
(b) both the second and third marbles drawn were white.

6 marbles in a bag, 2 are white the rest are red. The marbles
are removed from the bag one at a time. Let the random variable Y
represent the draw from the bag in which the last white marble has
been drawn. Determine the probability distribution of Y.
