On a windy day, out of every 3 sand dunes formed, only 1 remains. Out of 5 blown-out
sand-dunes, 1 has treasure and only 2 out of 3 sand dunes formed have lucky coupons. Find
the probability that the blown-out sand dune will contain both the things. Choose the correct answer:
A) 2/25  B) 4/75  C) 7/75  D) 3/5  E) 4/45
Probability of sand dune blown out = 2/3   Probability that it has treasure = 1/5   Probability that it has lucky coupon = 2/3   total probability = 2/3 * 1/5 * 2/3 = 4/45   ANSW4/45R:4/45
