The formula for the Expected Value for a binomial random variable is: P(x) * X. X is the number of trials and P(x) is the probability of success. For example, if you toss a coin ten times, the probability of getting a heads in each trial is 1/2 so the expected value (the num...

This is technically the weak law of large numbers, which holds in more cases than does the strong law. (back) This number is easily computed by the normal approximation to the binomial distribution. With CheapRelieve, mu = 0.5*10,000 = 5,000, sigma = [10,000*0.5*(1-0.5)](1/2) ...
