It must be the time (after midnight) as I have a blackout.

I have a matrix with some missing values I want to fill. for a certain cell, I know that the marginal row probability has mean r (more specifically, the marginal row probability follows the beta distribution with some parameters I know). the marginal column distribution of that cell has mean c (it follows a beta distribution with different known parameters)

what value should I "plug" in that cells (or which probability to sample from, in filling that value?)
