The power set is countably infinite QUESTION 18 An "eyes-only" diplomatic message is to be transmitted as a binary code of zeros and ones. If a zero is sent, it will be correctly received as a zero 95% of the time. If a one is sent, it will be incorrectly received as a zero 10% of the time. The text being sent is thought to be 70% ones with the remainder zeros. Suppose the next signal that is sent is received as a one. What is the probability that it was sent as a zero? a. 0.015 (3dp) O b. 0.3 O C. 0,023 (3dp) O d. 0,070 (3dp)
