WebIf you take a sample of the binomial distribution the mean of that sample will not (often) be 42 * 0.76. Instead, "On Average" the mean of the samples will be 42 * 0.76. The reason that the number of samples matters is because you are dealing with a small sample of the population. Take it to the extreme to see how this would work. Sample size n ...
