b) What is the probability that there are between 5 and 7 network failures inclusive in the next 24 hours?

c) What is the probability that there were 3 failures between 1:00 pm and 10:00 pm and there were no failures from 10:00 pm to midnight?

d) Let T be the time in hours until the next failure occurs. State the distribution and parameter(s) of T.

e) What is the probability that it takes between 1.5 and 4 hours until the next network failure?

f) The day shift IT supervisor comes in and notices that the log listing the network failures shows

3 failures between Midnight and 8:00 am, but the times of the failures were not recorded. What is the probability that at least 1 of the failures occurred between 2:00 am and 3:00 am?
