Abstract: An matrix with ones and zeros, which satisfies the Pólya condition, may be regular and singular for Birkhoff interpolation. We prove that for random distributed ones, is singular with probability that converges to one if , . Previously, this was known only if . For constant and , the probability is asymptotically at least .
