Suppose that there is a white urn containing three white balls
and one red ball and there is a red urn containing two white balls
and four red balls. An experiment consists of selecting at random a
ball from the white urn and then (without replacing the first ball)
selecting at random a ball from the urn having the color of the
first ball. Find the probability that the second ball is red.

9.84. Suppose an urn has b blue balls and r red balls. An
experiment consists of picking a ball at random from the urn, note
its color and then put it back into the urn and add one more ball
of the same color to the urn. Suppose we repeat this experiment
twice. What is the probability that we get a blue ball in the
second attempt?
