Probability histograp Probability histograms represent *chance*. Each class interval represents the probability an event would occur. As the number of repetitions increases, the closer the graphed data will appear to the calculated probability histogram.
The probability curve for the *sum of draws* will approximately follow the normal curve if the number of draws is large enough, even if the tickets in the box *do not *follow the normal curve.
When applying statistics to sums, it's usually in the form of *how much do we think the sum will add up to*, then compared against how much
