Q2. Two safety inspectors inspect a new building and assign it a "safety score" of 1, 2, 3, or 4. Suppose that the random variable X is the score assigned by the first inspector and the random variable Y is the score assigned by the second inspector, and that they have a joint probability mass function given in the following table: Y 1 2 3 4 0.09 0.02 0.2 0.02 2 0.01 0.1 0.1 0.03 3 0.04 0.01 0.04 0.2 4 0.01 0.02 0.1 0.01
