SOLVED: A truncated discrete distribution is one in which a particular class cannot be observed and is eliminated from the sample space. Specifically, we consider a zero-truncated random variable XT, which comes from a random variable X ranging from 0 to 2. However, the 0 class cannot be observed. Then, the pmf of XT is given by P(XT = 2) = P(X > 0) / P(X > 0) = 1.2%. Find the mean and variance of XT if X follows a Poisson distribution with parameter A.
