              			General formulas are deduced for calculating the correlation of a random process with a
functional over it. These formulas yield closed equations for the probability densities of
dynamical systems with random parameters. Parametric resonance in a system whose
eigenfrequency is a random function of the time is considered as an example. An equation
of general form is obtained for the joint probability density of the coordinate and velocity,
this going over into the Einstein–Fokker equation if the frequency is a Gaussian $\delta$-correlated
function of the time and into the Kolmogorov–Feller equation if the frequency is a generalized
Poisson $\delta$-correlated random process.
