You have a large jar that initially contains 30 red marbles and 20 blue marbles. we also have a large supply of extra marbles of each color. draw a marble out of the jar. if it's red, put it back in the jar, and add three red marbles to the jar from the supply of extras. if it's blue, put it back into the jar, and add five blue marbles to the jar from the supply of extras. do this two more times. now, pull a marble from the jar, at random. what's the probability that this last marble is red? what's the probability that we actually drew the same marble all four times?
