Question:

Each millisecond at an Internet router, a packet independently arrives with probability p. Each packet is either a data packet (d) with probability q or a video packet (v). Each data packet belongs to an email with probability r. Let. N equal the number of milliseconds required to observe the first 100 email packets. Let T equal the number of milliseconds you observe the router waiting for the first email packet. Find the marginal PMF PT(t) and the conditional PMF PN|T(n|t). Lastly. Find the conditional PMF PT|N(t|n).
