A retail store has implemented procedures aimed at reducing the number of bad checks cashed by its cashiers. The store's goal is to cash no more than eight bad checks per week. The average number of bad checks cashed is 19 per week. Let x denote the number of bad checks cashed per week. Assuming that x has a Poisson distribution: (a) Find the probability that the store's cashiers will not cash any bad checks in a particular week. (Round...
