Given the symbols A, B, C, D, E, F, G and H with the probabilities$\frac{1}{30}, \frac{1}{30}, \frac{1}{30}, \frac{2}{30}, \frac{3}{30}, \frac{5}{30}, \frac{5}{30}$ and $\frac{12}{30}$respectively. The average Huffman code size in bits per symbol is
- $\frac{67}{30}$
- $\frac{70}{34}$
- $\frac{76}{30}$
- $\frac{78}{30}$
