Distribution ofthe random discrete variable X with prob-abilities is presented in Table 1, where probabilities p2, p4>O and p4 is twice as large asp2. Distributionoftherandom discrete variable Y with probabilitiesis presentedin Table 2, where probabilities P1, P4> O and p1 is 1.6 times larger than p4.
