An information source generates symbols at random from a four-letter alphabet

An information source generates symbols at random from a four-letter alphabet a, b, c, dy with probabilities Pr[a] = 4/9. Pr= 3/9. Pr[c] = 1/9, Pr[d = 1/9. A coding scheme encodes these symbols into binary codes as follows: a:0 b: 10 c: 110 d: 111 Compute the expected length of the encoding of n letters generated by the information source. You may use any method you like, but must show your work/justify your
