CSE 4th SEM MA6453 PQT – PROBABILITY AND QUEUEING THEORY

Previous Year Question Papers

2. Suppose that on an average in every three pages of a book there is one typographical error. If the number of typographical errors on a single page of the book is a Poisson random variable. What is the probability of at least one error on a specific page of the book?

3. The joint probability mass function of a two dimensional random variable (X,Y) is given by p(x,y) =k(2x+3y), x=0,1,2 y=1, 2,3. Find the value of k.

4. What do you mean by correlation between two random variables?

5. What is a random process? When do we say a random process is a random variable?

6. Is Poisson process stationary? Justify.

7. Draw the state transition rate diagram of a M/M/C queueing model. 8. What is the probability that a customer has to wait more than 15 minutes to get his service completed in

8. What is the probability that a customer has to wait more than 15 minutes to get his service completed in a M/M/1 queueing system, if λ=6 per hour and µ=10 per hour? 9. State Jackson’s theorem for an open network. 10. What

9. State Jackson’s theorem for an open network. 10. What do the letter in the symbolic representation M/G/1 of a queueing model represent?
