5. a) Suppose that telephone calls arrives randomly through out the day at an office at
an avg. rate of three calls per 2 minutes. Assuming this is to be a Poisson
process:
i) How many calls expected ranging from 2.00pm to 2.10pm.
ii) What is the probability to receive more than three calls ranging from 2.00pm to
2.02pm?
iii) What is the probability to receive more than three calls ranging from 2.15pm to
2.19pm?
b) explain about M/M/C Queues. [12]
6. a) discuss about Alpha /Beta trackers.
b) explain about multi dimensional optimization. [6+6]
