The paper "Effects of 2,4-D Formulation as well as Quinclorac on Spray Droplet Size and Deposition"† investigated the effects of herbicide formulation upon spray atomization. A figure in the paper suggested the normal distribution with the mean 1050 µm and standard deviation 150 µm was reasonable model for droplet size for water (the "control treatment") sprayed through a 760 ml/min nozzle.
(d) If the sizes of the five independently selected droplets are measured, determine the probability that at least one exceeds 1440 µm? (Round your answer to four decimal places.)
