Question: 6. In many communication systems, a receiver will send a short signal back to the transmitter to indicate whether a message has been received correctly

6. In many communication systems, a receiver will send a short signal back to the transmitter to indicate whether a message has been received correctly or with errors. (These signals are often called an acknowledgement and a negativeacknowledgement, respectively. Bit checksum and other tools are used by the receiver to determine the absence or presence of errors.) Assume we are using such a. system in a. noisy channel, so that each message is sent errorfree with probability 0.86, independent of all other messages. (a) (4 points) What is the probability that in 10 transmissions, exactly 8 will succeed
