Please solve this problem urgently I will up vote.

3.11 Two sensors record a set of correlated data. Assume that the two bit strings, X and Y, differ in 5% of places, randomly distributed. (a) Find H(Y X). X is transmitted directly to the common receiver, but Y is decoded using a binary (31, 21, 5) code. (b) How many errors can the code correct? (c) Explain how Y can be reconstructed from X and the syndrome if the number of disagreements is at most the number of errors corrected by the code. (d) What happens if the difference between the bit streams exceeds this value
