A binary symmetric channel with p as transition probability, uses repetition code 'n' times, with n = 2m + 1 being an odd integer. In a block of n bits, if the number of zeros exceed number of ones, decoder decodes it as "0" otherwise as "1". An error occurs when m + 1 or more transmission out of 3 are incorrect, what is the probability of error?
