In this chapter, you will learn about random variables and sampling models exploring an example looking at various aspects of the game of chance American Roulette. In this chapter, you will learn about the fundamentals of discrete probability through looking at examples of sampling from an urn with and without replacement. In this chapter, you will learn about the Central Limit Theorem and compare results from Monte Carlo simulations to those obtained using the Central Limit Theorem for games of chance. 1) Let A and B be events on the same sample space, with P (A) = 0.6 and P (B) = 0.7. Probability theory is the mathematical foundation of statistical inference which is indispensable for analyzing data affected by chance, and thus essential for data scientists. R is a programming language and environment that is used in many fields for statistical analysis. The latest version is 3.6.0.
