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​).

The events "T" and "H" are INDEPENDENT;  therefore


    P(TH) = P(T)*P(H) = 0.45*0.55 = 0.2475.      ANSWER

Solved.
