To compute a Poisson probability with your calculator, press [2nd] then [VARS] to select DISTR and scroll down to poissonpdf or poissoncdf and press [ENTER]. The syntax is poissonpdf(μ, x), where μ is the occurrence rate on the given interval, and x is the desired number of successes. For “at-most” and “at-least” problems, follow a similar idea to the binomial tutorial above. Customers enter a store according to a Poisson process at a rate of 16 per hour. (a) How likely are we to see exactly 30 customers in a two-hour period? Hint: μ = 16 × 2 = 32 customers per two-hour period. (b) How likely are we to see at least 24 customers in a two-hour period?
