There is a machine at the coffee bar in the student center that permits a student
to place an order for a coffee drink via their cell phone. The machine produces paper tickets for
the baristas following a Poisson process at a rate of 2 orders per minute during the morning hours
(8:00a through 11:00a). What is the probability that exactly 360 orders will appear between 8:00a
and 11:00a with exactly 6 of them appearing between 10:30a and 11:00a? Please don't estimate using normal approximation as numerical answer is not needed, please leave it in Poisson form (e^x)(x^y/y!) Thanks!

STAT_14_2 In learning center there is a coffee machine for student service. The number of machine faults is split into Poisson distribution. On a normal day the number of faults is 1 per day and on a busy day the number of faults is 3 per day. The probability that a day is a busy day is 0.3, independently of other days. A. What is the probability that in normal three days there will be at least 2 faults all...
