   4.Using BSC model, evaluate the probability that

        a.11010 was transmitted and 10110 was received 
        b.exactly three bits are in error in the received signal of (a) 
        c.exactly any three consecutive bits are in error in the received
          signal of (a)

   5.The information message 

     M = 11100011 

     is to be transmitted using the generator polynomial

     g(x) = x5+x4+x+1 (5 and 4 are superscripts; i.e., x raised to the power
                       of) 

     with the remainder of 

     r = 5.

     What is the transmitted bit sequence?
