Answer correctly and explain clearly and without copying from internet

(3.b) Stochastic System Modeling. n a network node represented by an M/M/I model, the incoming packet rate is 2 - 1,000 packets per second (p/s) and the service rare is / = 5,000 p/s. (3.b.i) (2 points) Find the utilization value. (3.b.ii) (2 points) Find the average number of packets in the node. (3.b.iii) (2 points) Find the probability that there are 3 packets in the node. (3.b.iv) (2 points) Find the total packet delay in the node. (3.b.v) (2 points) Find the chance that this node becomes fully congested (show a proof)
