In a digital communication system, transmissions of successive bits through a noisy channel are assumed to be independent events with error probability p. The probability of at most one error in the transmission of an 8-bit sequence is

A. $$\frac{{7\left( {1 - p} \right)}}{8}+\frac{{7\left( {1 - p} \right)}}{{8 + \frac{p}{8}}}$$

B. (1 - p)⁸ + 8p(t - p)⁷

C. (1 - p)⁸ + (1 - p)⁷

D. (1 - p)⁸ + p(1 - p)⁷
