BU275 Study Guide - Final Guide: Exponential Distribution, Emv, Standard Deviation
Document Summary
In a night, the diners arriving at the restaurant follows an exponential distribution with rate 4 per twenty minutes. D) will be less than the probability that the interval of arriving is between 10 to 15 minutes. In the restaurant mentioned in question one, diners arrive at the rate of 4 per twenty minutes following a poisson distribution. What is the probability of 3 arrivals in twenty- minute interval: still in this same restaurant in question one and two, diners arrive at the rate of 4 per twenty minutes following a poisson distribution. Same restaurant that in question one, two and three, diners arrive at the rate of 4 per twenty minutes following a poisson distribution. Suppose the 41st diner arrive at time t1 and 42nd diner arrive at time t2, what is the probability that t2-t1> 10 minutes: e-4, e-2, 1 e-4.
