Communications $-$ Source Coding $2$

Question $13$ of $25(2$ Points$)$

Not answered

A discrete, memoryless, binary source provides symbols xin$\{A,B\}$ with probabilities $Pr\{x=A\}=0\mathrm{.}7$ and $Pr\{x=B\}=0\mathrm{.}3.$ In order to transmit the data, a Huffman coding with source words consisting of three symbols shall now be applied.

Select a correct Huffman tree for source words given in the previous question.
