2. There are two boxes. Box A has 3 white chips and 1 red chip, Box B has 2 white chips and 1 red ch There is a 40% chance that Box A will be the first box selected (that is, there is a 60% chance that Box B will be selected first.) A box is chosen at random. From the first box chosen, a chip is selected at random, the color is observed, and then the chip is placed in the other box (the one not chosen first). A chip is then selected at random from the other box and the color is observed. a. Find the probability of observing 2 red chips in a row. b. Find the probability of observing a white chip from the other box (the last box chosen)

Question
2. There are two boxes. Box A has 3 white chips and 1 red chip, Box B has 2 white chips and 1 red chip.
There is a 40% chance that Box A will be the first box selected (that is, there is a 60% chance that
Box B will be selected first.)
A box is chosen at random. From the first box chosen, a chip is selected at random, the color is
observed, and then the chip is placed in the other box (the one not chosen first). A chip is then
selected at random from the other box and the color is observed.
a.
C.
Find the probability of observing 2 red chips in a row.
b. Find the probability of observing a white chip from the other box (the last box
chosen).
Given that one observes a white chip from the other box, find the probability that
Box A was the first box chosen.
