A Sample of Stochastic Simulation of an Automatic Teller Machine

With appropriate assumptions, this paper gives a stochastic model on the ATMs which provide cash service to the people who need to get money from the bank and gives a formula which can offer the gross of the money provided to the people when the number of people obeys Poisson distribution and the the quantity of money obeys Normal distribution. Besides, this paper gives a conclusion with stochastic simulation.
