When you set prob=TRUE you get a ***density*** scale. The resulting
histogram represents a probability density function (directly comparable
with the normal density function you sought to superimpose) which
***integrates*** to 1. The values of a density funcion need not
be less than 1; these values are not probabilities. They are probability
densities. Roughly if f(x) is the p.d.f. for X then
f(x) dx approx. = P(x <= X <= x + dx)
I.e. f(x) dx will be less than 1, but f(x) on its own need not be.
O.K.?
