The daily number of accidental disconnects with a server fol

The daily number of accidental disconnects with a server follows a Poisson distribution. On five days accidental disconnects are observed. Obtain the maximum likelihood estimate of A. Find the maximum likelihood estimate of the probability that 3 or more accidental disconnects will occur.

Solution

Average = 20/4 =5

Hence MLE of lemda = 5

P(X>=3) = 0.8753
