answer all questions with explanation

1.7 Consider the random discrete population described by the probability mass function fx(x) =x/10 x= l, 2, 3, 4. A sample of n = 3 observations is drawn at random and without replacement from this dis- tn'bution. (After x1 = 2, for example, is observed, the next observation is drawn from a conditional probability mass function that excludes 2). (:1) Find the P(X(2) = 2) by halld. (b) Find the P(X(2) = 2) using APPL. (c) Verify the two results above using Monte Carlo simulation
