Textbook Problem

Consider a communication source that transmits packets containing digitized speech. After each transmission, the receiver sends a message indicating whether the transmission was successful or unsuccessful. If a transmission is unsuccessful, the packet is re-sent. Suppose a voice packet can be transmitted a maximum of 10 times. Assuming that the results of successive transmissions are independent of one another and that the probability of any particular transmission being successful is *p*, determine the probability mass function of the rv *X* = the number of times a packet is transmitted. Then obtain an expression for the expected number of times a packet is transmitted.
