The daily number of accidental disconnects with a server follows a Poisson distribution. On live days 2 5 3 3 7 accidental disconnects are observed. Obtain the maximum likelihood estimate of lambda. Find the maximum likelihood estimate of the probability that 3 or more accidental disconnects occur. Solution Average = 20/4 =5 Hence MLE of lemda = 5 P(X>=3) = 0.8753.
