Yet another variation: A better packet switched network employs the concept of acknowledgment. When the end user’s device receiv

es a packet correctly it sends an acknowledgment to the sender. Here too, a packet is received correctly with probability p, but the sender keeps sending copies of a given packet until a copy is correctly received (signaled by acknowledgment). Let random variable N be the number of times the same message packet is sent. a) Find the PMF PN (n). b) To avoid excessive delays (too many repeated transmissions of same packet), it is required that the network maintain P[N < 4] > 0.95. Find the minimum value of p that will satisfy this requirement

PLZ HELP!!!
mariarad [96]
Answer: A. Usability testing
Explanation:
Usability testing would be the correct answer because if the user interface isn't "frendly" then people won't be able to use it properly. Or if you are refering to the word friendly as looking safe, then even more so would be usability testing. Because if people don't like the fonts and styles of the user interface, they might not use it at all.
