2) Let, A be set of workers and B. be set of Job. Let R1 be relation from A to B (a,b) is in [we assume be a binary relation from A B such that R₁. If worker 'A' is assign to job B. that worker might be assign to same Job] Let R2 be a binary relation on A such that (b1, b2) is in R2. It b1, b2 can get along each other if a they are assign to same job. State condition in terms of R₁, R2 and (possiably binary relation derived from R1 and R2 Such that assignment of worker in the job according to R1 will not took of worker that can't get along with one another on the same job.

a simple binary communication channel carries messages by using only two signals; say 0 and 1. We assume that; for a given binary channel, 40% of the time a 1 is transmitted; the probability that a transmitted 0 is correctly received is 0.90,and the probability that a transmitted 1 is correctly received is 0.95. given 1 is received, probability that 1 was transmitted
