When a random experiment is conducted, the probability that event A occurs is 1/5. If the random experiment is conducted 5 independent times, what is the probability that event A occurs exactly twice?
Choices:	A) 36/625	B) 48/625	C) 64/625	D) 98/625	E) 128/625
One case is: 1/5*1/5*4/5*4/5*4/5=64/3125   The total number of possible cases is 5C2 = 10   P(event A occurs exactly twice) = 10*(64/3125) = 128/625   The answer is 128/625.
