In the process of manufacturing crystal tubes air ball may be trap in the tubes. Anexperience designer believes that the number of air ball trap in a tube follows a Poissondistribution with mean -5.Salable tubes are categorized as A Grade if no air ball aretrap 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 Graderespectively?(b)Find the probability that a tube manufactured is not salable.
