Abinary communication channel transmits a sequence of "bits" (0sand 1s). suppose that for any particular bit transmitted, there isa 10% chance of a transmission error (a 0 becoming a 1 or a 1becoming a 0). assume that bit errors occur independently of oneanother.

a.) consider transmitting 1000 bits. what is the approximateprobability that at most 125 transmission errors occur?

b.) suppose the same 1000-bit message is sent two different timesindependently of one another. what is the approximate probabilitythat the number of errors in the first transmission is within 50 ofthe number of errors in second?
