John tossed a fair coin 5 times. What is the probability that the coin landed heads up exactly twice?
Select the correct option:	A) 0.156	B) 0.256	C) 0.35	D) 0.456	E) 0.555
The probability is exactly same as the cion landed tail up once. That is 5*(1/2)^5 = 5/32 =0.156.   The answer is, therefore, (0.156).
