The probability is 0.6 that an “unfair” coin will turn up tails on any given toss. If the coin is tossed 3 times, what is the probability that at least one of the tosses will turn up tails? Choose the correct option.
A) 0.064	B) 0.36	C) 0.64	D) 0.784	E) 0.936
probability that at least one of the tosses will turn up tails = 1 - probability that all will be heads   = 1 - (0.4*0.4*0.4)   = 1 - 0.064=
