The number of misprint on one page of the galley proof of a book has a Poisson distribution with mean 2.1.(a) Find the probability of the number of distribution.(b) Find the probability that a randomly chosen page contains at most 4 misprints. ( 0.937874 )(c) Find the probability that a randomly selected page contains between 2 and 4 misprints, inclusive. (0.937874 – 0.379615 )(a) How many misprints will be expected on two pages? In addition, find the standarddeviation of the number of misprints on two pages. (4.2, 4.2 )(e) Find the probability that two randomly chosen pages contain exactly 3 misprints. (0.185165 )
The parentheses in each questions are answers, please explain how to get that answer.
