If the number of customers received by the parlour follows a Poisson distribution, To Find the approximate probability that 16 customers will be coming to the parlour in a particular 4-minute period on a given day Solution: an average rate of 4 per minute. => an average rate of 4* 4 per 4 minute. => an average rate of 16 per 4 minute. Hence mean = 16 λ = 16 = P(x) = λx e^(-^) / x! P(16) = 16¹6e-16/16! = 0.099 = 0.1
