Q1. A series of messages is to be transferred between two computers over the Internet. The messages comprise just the characters A through H. Analysis has shown that the probability (relative frequency of occurrence) of each character is as follows: A and B= 0.25, C and D= 0.14, E,F,G, and H= 0.055 (a) By computing the entropy of the source, derive the minimum average number of bits per character.
