An urn contains 20 red balls and 40 blue balls. two are chosen at random, one after the other, without replacement. (round your answers to one decimal place.) (a) use a tree diagram to calculate the following probabilities: the probability (as a %) that both balls are red 33 x % the probability (as a %) that the first ball is red and the second is not 33 x % the probability (as a %) that the first ball is not red and the second is red the probability (as a %) that neither ball is red (b) what is the probability (as a %) that the second ball is red? % (c) what is the probability (as a %) that at least one of the balls is red?
