I found this question fascinating:
A barber with a one-man barbershop takes exactly 30 minutes to complete one haircut. If customers arrive according to a Poisson process at a rate of one every 40 minutes, how long on the average must a customer wait for service?
The second one wont wait, the third one wont wait nor will the fourth one. No one will wait…
mean=∆ variance =∆ pmf=(∆^x(e^-x))/x!
Nimekimbia mbio thinking its something poisonous.
@Unataka kujua ili?
Sikufanya stats but by logic none will wait assuming anaingia direct after mmoja kumaliziwa.
I think for each customer the barber saves 10 minutes 10(n) N being the number of customers.
But let me research and see if I can prove it with the poisson process.
:DWhatever that is
Ferk…brain crump!
lw=^/u(u-^) =0.075
Hii ni hesabu ya probability!
poisson-fish
i would rather use Monte Carlo method
