We know that probability is simply the ratio of number of
successful event over number of total event. In case of succession of dependent
events, the overall probability is the product of each probability. In this
case, we have a total of 10 CD’s and 5 are jazz without replacement therefore:
Probability = (5/10) * (4/9) * (3/8) * (2/7)
Probability = 120/5040 = 0.0238
