One urn contains two pieces of candy{one green and one red. A second urn
contains four pieces of candy{one green and three red. For each urn, each piece of candy is
equally likely of being picked. You pick a piece of candy from each urn and eat the two chosen
candies.
If you eat exactly one piece of green candy, you draw a second piece of candy from the urn
still containing a green piece of candy. You now eat the candy you just chose. What is the
probability that you ate two pieces of green candy?	Options.
A) 1/8
B) 1/4
C) 3/8
D) 1/2
E) 5/8
There are four possibilities for the rst round:   You pick a green piece of candy from each urn. (Probability 1/2*1/4=1/8)   You pick the green piece of candy from the rst urn and the red piece of candy from the   second. (Probability 1/2 * 3/4 = 3/8 :) You have a 1/3 chance of eating the green piece of candy   on the second round (since three pieces of candy remain in the second urn, and one of   them is green.You pick the red piece of candy from the rst urn and the green piece of candy from the   second. (Probability 1/2 *1/4 = 1/8 :) There is only one more piece of candy in the rst urn,   so you eat it on the second round.   You pick a red piece of candy from each urn. (Probability 1/2 *3/4 = 3/8 .)   Your chance of eating two pieces of green candy is   1/8   +   3/8   1/3   +   1/8   =   3/8   correct answer 3/8
