    Since we have equal probabilities we can plot the possible payoffs in this game. In Fig. 1 we see the outcome of 1 and 2 tosses in Fig. 2 we see the outcome of 4 and 8 tosses and in Fig. 3 we see the outcome of 16 and 32 tosses. As we can observe, the coin-tossing game seems to lead in the limit to the normal distribution. If we change the probabilities, we will in the limit reach a Fig. 1 When tossing the coin one time we have two outcomes, À1 or 1, both with probability 1/2. When tossing the coin two times we have three outcomes, À2 with probability 1/4, outcome 0 with probability 1/2 26 Analytical Finance: Volume I Fig.

    In order to carry out this task we will need a variety of properly calibrated valuation models, and information about as many traded prices as possible. The next important task is to surmise how today’s accepted pricing methodology might change in the future. Notice that the expression ‘pricing methodology’ makes reference not just to the model, but also to the valuation of the underlying instruments, to its calibration, and possibly, to its numerical implementation. We should not assume that this dynamic process of change should necessarily take place in an evolutionary sense towards better and more realistic models and more liquid and efficient markets.
