λ=3 , mu = 5

<u>Explanation</u>:

λ=3

mu = 5

states

0 - no customers

1- 1 customre

2 - 2 customers

Set up Equations

Rate of entry = Rate of exit

5P1 =3P0

5P2 + 3P0 = 5P1 + 3P1

3P1 = 5P2

P0 + P1 + P2 = 1

solve the above

1a) = 0 into P0 plus 1 into P1 plus 2 into P2

b) λ ( 1 minus P2) by λ = 1 - P2

c) change the paramater mu = 5 into 2 and solve a) again
