    Kindly help me for Probability question

    Question is
    This problem illustrates some of the economic issues facing service providers as they migrate away fromvoice-only systems to mixed-media systems. Suppose you are a service provider with 120KHz of bandwidthwhich you must allocate between voice and data users. The voice users require 20Khz of bandwidth, and
    the data users require 60KHz of bandwidth. So, for example, you could allocate all of your bandwidth tovoice users, resulting in 6 voice channels, or you could divide the bandwidth to have one data channel and
    three voice channels, etc. Suppose further that this is a time-division system, with timeslots of duration
    T. All voice and data call requests come in at the beginning of a timeslot and both types of calls last Tseconds. There are six independent voice users in the system: each of these users requests a voice channelwith probability .8 and pays $.20 if his call is processed. There are two independent data users in the system:each of these users requests a data channel with probability .5 and pays $1 if his call is processed. Howshould you allocate your bandwidth to maximize your expected revenue?
