2. The average number of calls received by a switchboard in a 30-minute period is 5.
a. What is the probability that between 10:00 and 10:30 the switchboard will receive exactly 6 calls?
b. What is the probability that between 10:00 and 10:30 the switchboard will receive exactly 8 calls?
Please type or do not answer thank you! I have trouble reading written math.
The given problem is of Poisson Process.
Let the number of call received per 30 minutes be denoted by the random variable x.
It is given that = 5
The required probability is given by\
a) The probability that between 10:00 and 10:30 the switchboard will receive exactly 6 calls
We have a period (10-10:30) that is the standard 30-minute period. So,
So, the probability that between 10:00 and 10:30 the switchboard will receive exactly 6 calls is 0.14622.
b) The probability that between 10:00 and 10:30 the switchboard will receive exactly 8 calls.
So, the probability that between 10:00 and 10:30 the switchboard will receive exactly 8 calls is 0.06528.
