WebThis book has been written keeping all this in mind. We are developing a wide range of support to help you plan and teach the 2021-2023 syllabus. In this section, we will informally develop a few simple rules that govern the calculation of probabilities. First, the green ticket has to be drawn. Among the 1/3 of repetitions when green is drawn first, the red ticket has to be drawn next. Suppose you draw two tickets at random without replacement; that is, you shuffle the three tickets, draw one, shuffle the remaining two, and draw another from those two. In our earlier examples using Census data, we saw that the variable AGE had a value 100 that meant 100 years old or older. By convention, probabilities are numbers between 0 and 1, or, equivalently, 0% and 100%. It is a zero-player game, meaning that its evolution is determined by its initial state, requiring no further input. Introduction 1.1.1.
