Iowa Lottery Pick 3 Sum of Digits - Frequency and Last Appearance

The sum analysis for Iowa Pick 3 was performed on Wednesday, May 22, 2013 with 467 as the latest number. The sum of the digits of this number is 17.
The analyses results are summarized in the table below.

The first column of the table is the sum value. The second column lists how many Pick 3 numbers have a sum value of the first column. And what those numbers are will pop up when you place your mouse over it. (If you don't see the pop-up list, your browser might not support it; the same list is available here.) Note that only the box representations of the Pick 3 numbers are listed. For example, corresponding to a sum of 3, three numbers are listed (003, 012, 111). The first is a double, therefore has 3 permutations, the second is non-repeating, thus with 6 permutations, the triple has only one. So, 6 + 3 + 1 = 10 numbers have a sum of 3.

Both the Iowa Lottery Pick 3 'Frequency' and 'Last Appearance' parts of the above list contain the actual values as well as the expected values (rounded to their integral values). For the frequencies, a direct comparison of the two values will indicate if a Pick 3 sum is more, or less frequently drawn than expected. We have also introduced another column designated as "Factor", which indicates how high or low the actual frequency is compared to the expected value. If the "Factor" is greater than 1, it means that the Pick 3 sum is drawn more times than expected, and vice versa. If the two values are very close to each other, the Factor will be 1 or very close to 1.

The expected values of the "Last Appearance" culumn are actually how often that Iowa Pick 3 sum is expected to be drawn. For example, sums of 0 and 27 are expected every 1000 draws, while 13 and 14 should show up every 13 draws. A very late Pick 3 sum will have its actual value very much greater than the expected value. Just as an eye-catcher, we will show in blue those Iowa Pick 3 sums that are late by more than 1.5 times the expected time lapse, and in red, those that are late by more than twice this value.
