5. A cell phone uses a packet communication

5. A cell phone uses a packet communication system for transmitting voice data to a base station. Transmission errors occur with probability p. Such errors are detected by the base station. Every time the base station detects an error, it send a NAK (negative acknowledgement) to your cell phone. Every time the base station detects a correctly received packet, it sends an ACK (acknowledgement) to your cell phone. ACK's and NAK's are received without error by your cell phone. When your cell phone receives a NAK, it retransmits the packet. A packet may be retransmitted a maximum of d times. If the probability of a packet error is p, what is the PMF of T, the number of times a packet is transmitted
