(1 point) An urn has 3 red, 5 white, and 3 blue balls in an urn and two are drawn one after another without replacement. What is the probability that the two balls are both red given that they are the same color?
In an urn, there are 3 blue balls and 2 red balls. A ball is selected at random without replacement. Regardless of what color the first ball was, a blue ball is added to the urn (so there are a total of 5 balls in the urn now). Then a second ball is selected from the urn. a) What is the chance that the second ball selected from the urn is blue? b) Given that the second ball is blue,...
