Good day, Assume an event with a normally distributed numerical outcome. Call the outcome x. Assume that any outcome less than a particular value (called a) has a value of zero and any outcome greater than a has a value of x-a. Call the probability curve of the normal distribution f(x) and x-a = g(x). I am calculating the statistically probable value of any event as Integral from a to infinity of [f(x) times g(x)] dx Is this valid? I hope that I explained this sufficiently. Thank you for your help.
