Probability of photons reflecting or refracting

QuED

I understand that the probability of a photon refracting or reflecting between mediums is dependant on the photon's angle of incidence and the two medium's refractive indexes.

How can I calculate the probability of a photon reflecting instead of refracting for example, a sheet of glass at a 45 degree angle of incidence?

thanks

All the photon probabilities come from the classical EM Fresnel relations. These are given in most EM textbooks. The classical reflection (R) and transmission (T) coefficients derived from the Fresnel relations are just the photon probabilities.

in particular equations 1261 and 1262.
