Problem 1 A tablet computer transmits a file over a wi-fi link to an access point. Depending on the size of the file, it is transmitted as N packets where N has the PMF PN (n) = Sc/n n= 1,2,3, otherwise. (a) Find the constant c. (b) Sketch the PMF of the variable N (c) Find and sketch the CDF of the variable N (d) Each packet is received correctly with probability p, and the file is received correctly if all N packets are received correctly. Find P[C], the probability that the file is received correctly.
