A study publishes Selected Topics in Assurance Related Technologies (START) sheets to help improve the quality of manufactured components and systems. One START sheet focuses on a particular component. The number of components that fail in any 30 comma 00030,000-hour period is assumed to follow a Poisson distribution with a mean of 1.21.2. a. Find the probability that there are no component failures during the next 30 comma 00030,000 hours of operation. b. Find the probability that there are at least fourfour component failures during the next 30 comma 00030,000 hours of operation. a. The probability that there are no component failures during the next 30 comma 00030,000 hours of operation is . 301.301. (Round to three decimal places as needed.) b. The probability that there are at least fourfour component failures during the next 30 comma 00030,000 hours of operation is nothing.
