A student receiving texts can be modeled as a Poisson process at a rate of 3 per hour.
a) What is the probability that the student receives 2 or more texts in the next 30 minutes?
b) Given that the student received 3 texts in the last 10 minutes, what is the probability that the next text will arrive within 15 minutes?
c) Among a group of 10 students, what is the probability that at least 2 will receive at least one text within 15 minutes?

The arrival of customers to a store is modeled as a poisson process with an intensity of 12 customers / hour. a) Assume that there have been 4 customers in 15 minutes. Calculate the probability that at least two customers arrived in the first 10 minutes. b) Suppose the store is open for 10 hours a day. Approximately determine the probability that at least 100 customers arrived during this day.
Warnings of a possible virus attack on a particular laptop can be modeled as a Poisson process with 1 warning per hour. a) A person received 3 warnings in the last 1 hour of which 1 warning was 15 minutes back. What is the probability that this person has to wait for more than 3 hours for his next warning? b) In a 3-hour software update going on a laptop of 200 people, what is the probability that less than...
suppose that visits to a website can be modeled by a Poisson
process with a rate λ=10 per hour
(a) What is the probability that there are more than or equal to
2 visits within a given 1/2 hour interval
(b) A supervisor starts to monitor the website from the start of
a new shift. then what is the expected value of time waited by the
supervisor until the 10th visit to the website during that
shift?
Suppose that visits...

question b
The arrival of trucks at a receiving dock is a Poisson process with a mean arrival rate of 2 per hour. a. Find the probability that exactly 5 trucks arrive in a two-hour period. b. Knowing that there were 5 trucks arrived during the first two-hour period, find the probability that exactly 5 trucks will arrive in the next two-hour period.
