Let us start with the solution.
00:01
So, for m m 1 model, the average waiting time in the queue is 39 minutes, right? and the average service time is equal to 16 minutes, right? we need to find inter arrival time, that is, average inter arrival time is equal to what? okay.
00:48
So, we have been given the waiting time, that is, w a, this is lambda by mu, mu minus lambda, this is equal to 39 has been given to us.
01:03
And the average service time is given as 16, that is, 1 by mu, right, is given to us.
01:12
So, mu is equal to 1 by 16, right? so, what we have to find is, we need to find average inter arrival time, that is, 1 by lambda is equal to what? this we have to find, right? we have lambda by mu, mu minus lambda is equal to 39...
