Please answer all In a 400-page manuscript, there are 100 random misprints. Assume that these misprints are distributed following Poisson distribution. (1) If a page is selected, find the probability that it has no misprints. (2) How many pages in the manuscript are there with one misprint? (3) If two pages are selected, find the probability that they have one misprint. (4) If four pages are selected, find the probability that they have at least 1 misprints..
