A few days ago I wrote about the expected number of roots in a random polynomial where each coefficient is drawn from a standard normal, i.e. a Gaussian distribution with mean 0 and variance 1. Another class of random polynomials, one that comes up in applications to physics, draws each coefficient from a different distribution.
