a) find p(0)= b) find p(1)= c) find p(2)= d) find p(3)= Researchers studied the problem of sampling mail a. Find p(0). rooms for the presence of anthrax spores. Let x equal the number of mail rooms contaminated with p(0) = anthrax spores in a random sample of n mail rooms (Round to four decimal places as needed.) selected from a population of N mail rooms. The probability distribution for x is given by the formula N -K n-x P(x) = where k is the number of contaminated mail rooms in the population. Suppose N = 200, n = 3 and k = 30
