Estimate the balking rate, Operating System

People arrive at a barber shop at the rate of one every 4.5 minutes. If the shop is full (it can hold five people altogether), 30% of the potential customers leave and come back in 60 ± 20 minutes. The others leave and do not return. One barber gives haircut in 8 ± 2 minutes, whereas the second talks a lot and it takes 12 +/- 4 minutes. If both barbers are idle, a customer prefers the first barber. Treat customers trying to reenter the shop as if they are new customers. Simulate the system until 300 customers have received the haircut.
