Multiple choice

Consider a binary symmetric channel (BSC) with probability of error being p. To transmit a bit, say 1, we transmit a sequence of three 1s. The receiver will represent 1 if at least two bits are 1. The probability that the transmitted bit will be received in error is

  1. p3 + 3p2 (1 - p)

  2. p3

  3. (1 - p3)

  4. p3 + p2 (1 - p)
