(7' points) Let there be a set of 50 calculators in a box out of which 10 are defective. Suppose we make a random selection of 30 calculators from the box and let X be the random variable that. records the number of defective calculators in our selection. Compute distribution of X. {Helpful suggestion: Don't try to compute the probability for all possible values of X separately. Instead, try to write down a general form.)
