# Question: With reference to Exercise 3 97 In exercise Two textbooks are selected

With reference to Exercise 3.97,

In exercise

Two textbooks are selected at random from a shelf that contains three statistics texts, two mathematics texts, and three physics texts. If X is the number of statistics texts and Y the number of mathematics texts actually chosen, construct a table showing the values of the joint probability distribution of X and Y.

Find

(a) The marginal distribution of X;

(b) The conditional distribution of Y given X = 0.
