I was reading Feynman's book on QED and I stumbled upon the probability of reflection of photons by a piece of glass. Is there a way to calculate the probabilty of reflection?enter image description here

Yes. This is contained in Maxwell's equation. The probabilities are obtained from Fresnel's coefficients, and depend on the angle of incidence, as you can read here.

There is also this nice set of slides that also gives quite a bit of details on how these are calculated from Maxwell's equations.
