Question 1164188: Many everyday decisions, like who will drive to lunch or who will pay for the coffee, are made by the toss of a (presumably fair) coin and using the criterion "heads, you will; tails, I will." This criterion is not quite fair, however, if the coin is biased (perhaps due to slightly irregular construction or wear). John von Neumann suggested a way to make perfectly fair decisions, even with a possibly biased coin. If a coin, biased so that P(h)=0.4500 and P(t)=0.5500, is tossed twice, find the probability P(th). Answer by ikleyn(52884) (Show Source): You can put this solution on YOUR website! .
The events "T" and "H" are INDEPENDENT; therefore
P(TH) = P(T)*P(H) = 0.45*0.55 = 0.2475. ANSWER
