we should also expect varied distribution

we should also expect varied distribution.If you toss a coin one hundred times,you would expect to get heads somewhere around 50% of the time.But if your results started to approach 100% heads,you'd suspect that something was wrong,not with your individual flips,but with the coin itself.Of course, suspect identifications aren't as random as coin tosses,but they're not as clear cut as telling apples from bananas, either.
