                                                    to put this in perspective, the actual difference here is 513 – 468 = 45 out of a
                                                    total of 4,839 numbers drawn. In terms of percentages, the difference between
                                                    the number of times the number 1 and the number 2 are drawn is 45 ÷ 4,839 =
                                                    0.009, or only nine-tenths of one percent.
