A message is transmitted using a binary code of Os and 1s. Each transmitted bit (0 or 1) must pass through three relays before reaching a receiver. At each relay, the probability is .20 that the bit sent is different from the bit received (a reversal). Assume that relays operate independently of one another. Transmitter -> Relay 1 -> Relay 2 -> Relay 3 -> Receiver If a 1 is sent from the transmitter, what is the probability that a 1 is sent by all three relays?

A message is transmitted using a binary code of 0s and 1s. Each transmitted bit (0 or 1) must pass through three relays before reaching a receiver. At each relay, the probability is 0.20 that the bit sent is different from the bit received (a reversal). Assume that relays operate independently of one another.
