    Games with Dice

    In this chapter, we explore games in which dice are rolled, including Yahtzee, Settlers of Catan, and Craps. You will learn tools such as using built-in R functions to calculate combinatorics, and using functions such as replicate and the %in% operator.

    Poker

    This chapter explores questions in poker, including the most often televised version of Texas Hold'em. We will learn to code for win probabilities with any given number of outs, and also explore a more theoretical model of poker known as the von Neumann model. We will learn to use functions such as Reduce, runif, and ifelse.

Probability of a large straight

A large straight occurs when the five dice land on consecutive denominations, specifically either {1,2,3,4,5} or {2,3,4,5,6}.

Let's calculate the probability of a "large straight" in a single roll of the five dice.
