A bag contains 120 identical balls (e. g., in size, shape, and weight) except their color. Of the 120, 90 balls are red and 30 balls are green. We can not see inside the bag. Two balls are chosen at random without replacement. Calculate the following probabilities.
(a) What is the probability that the first ball chosen is red?
(b) What is the probability that both balls are red?
(c) What is the probability that at least one ball is red?
(d) What is the probability that the second ball chosen is green?
(e) What is the probability that the first ball chosen is red given that the second ball is green?
