the probability that the blown-out sand dune will contain both the things.  Answers:	A) 2/25	B) 4/75	C) 7/75	D) 3/5	E) 4/5
Probabilty of sand dune blown out = 2/3   Probabilty that it has treasure = 1/5   Probability that it has lucky coupon = 2/5   total probability = 2/3 * 1/5 * 2/5 = 4/75   ANSWER:4/75
