Question

Consider a discrete random variable X that takes values from the set S = {0, 1, 2, 3}, being the number of individuals of a species within a habitat. Consider the probability distribution of X with Pr(X = 0) = 0.15, Pr(X = 1) = 0.25 and Pr(X = 3) = 0.5, where Pr denotes probability. The value of Pr(X = 2) is _______. (Round off to two decimal places)
