IF 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?
Options:
A) 0.064

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=
