Thank youAnswer by stanbon(57962)   (Show Source): You can put this solution on YOUR website!If three coins are tossed what is the probability of tossing two heads and one tail? ---------- There are three ways to place the tail so those three are mutually exclusive events. The probability of each event is (1/2)^2*(1/2) because each coin is independent = 1/8 So the answer is 1/8 + 1/8 + 1/8 = 3/8 ------------ Using the binomial formula you would get 3C2(1/2)^2(1/2) = 3(1/8) = 3/8 ==================== Cheers, Stan H.
