) State the gambler's ruin problem. Formulate a mathematical model to estimate 4 the probability of avoiding ruins. How random walks can be used to calculate of the ranks of the pages in a Web- 3+3 graph? Illustrate how it work with the following Web-graph where (hyper)links are represented by directed edges. Demonstrate at least four iterations of the ranked matrix. ) State the gambler's ruin problem. Formulate a mathematical model to estimate 4 the probability of avoiding ruins.
