Thank you for your brief explanation. Some teachers just want us to memorize the formula without explaining the theory behind it so we're not able to enjoy the beauty of the knowledge. But you explained it very well. Thank you :)

[@YungGudGalaxy]

At 9:00 can't you just do P(n≥k) = p^k (which is 8/9^2) to get the answer?

[@nativeguy5564]

Nope because he has to find the probability of n customers greater than and equal to the value of k. So therefore probability of all the customers greater than and equal to the k is added up.

Hii everyone, I am graduation student . My project topic is " an outlook on single server queueing models". I knew nothing about this topic .This lecture gave me the basics .but I don't know how to sort the chapters of my project. Anyone know how to sort this as four chapters ? Please suggest me some textbooks also. please help me.

[@thefrozenheart6407]

Can anyone tell me how he found the value of Ls=3.856

[@afiffrizki1092]

by using the formula given, it would take time to calculate normally.
