In the process of manufacturing crystal tubes air ball may be trap in the tubes. An experience designer believes that the number of air ball trap in a tube follows a Poisson distribution with mean 0.15. Salable tubes are categorized as A Grade if no air ball are trap and B Grade if one or two air balls are trapped. (a) How many percent of the tubes are classified as A Grade and B Grade respectively? (b) Find the probability that a tube manufactured is not salable. 2.
