I need your help with this question. Please help me by answering and showing explanation.

Problem 1. There are two types of trafc accidents, those causing minor damage and those causing major damage. Let X represent the number of minor damage accidents at a particular location in a given year, and Y the number of major accidents. The joint PMF of X and Y is as follows: 0.05 0.06 0.05 0.02 0.01 0.07 0.15 0.04 0.03 0.01 0 1 2 0.04 0.05 0.10 0.04 0.05 3 0.01 0.04 0.06 0.07 0.05 (a) What are the marginal pmfs of X and Y? (b) What are Cov(X, Y) and pr? (c) What is the probability that the numbers of major and minor accidents differ by 2? ) (d What is the probability that there are an equal number of major and minor accidents
