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,d with probabilities Pr[a] 5/9. PT2/9, Pr[e]1/9, Prld-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
