colored balls from two bags. Assume that each bag contains 4 balls. Bag
a contains 2 red and 2 white, while bag b contains
2 red, 1 white, and 1 blue. You randomly select
one ball from bag a, note the color, and place the ball in bag b. You then
select a ball from bag b at random and make note of its color.
(1) What is the probability that both balls are red?
(2) What is the probability that both balls are red given
that the first ball you drew was red?

the probability that both balls are red are:4/8 0r 1/2
