District Of Columbia Lottery DC-4 Sum of Digits - Frequency and Last Appearance
The District Of Columbia Lottery DC-4 sums analysis involves two sets of data. The first is the number of
times a sums is drawn for the entire history of the game while the second set is how many draws have
elapsed since a DC-4 sums's last appearance. Whether sums are included as a play type of the state's
game or not, these analyses coupled with others, such as digits and pairs analyses, will hopefully help
you select the numbers to play.
DC-4 sum analysis is more complex than digits or pairs analysis since "Not all sums are created equal".
Sum of 18 is the most likely to be drawn since it covers 670 numbers (see table below). On the other hand,
0 and 36 are the least likely since each covers only one number, 0000 and 9999, respectively. Therefore,
for every 10000 draws, while sums of 18 can fall 670 times, sums of 0 and 36 are expected only once.
A general description of 4-digit sums together with the sum values and the list of numbers having that sum can be found at
4-digit sums of this web site.
The sum analysis for District Of Columbia DC-4 was performed on Sunday, May 19, 2013 with 4756 as the latest number.
The sum of the digits of this number is 22.
The analyses results are summarized in the table below.
|Sum||How many Numbers|
have this Sum
The first column of the table is the sum value. The second column lists how many DC-4 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 DC-4 numbers are listed. For example, corresponding to a sum of 3, three numbers are listed (0003, 0012, 0111).
The first and the third are triples, therefore have 4 permutations each, and the second is a double, thus with 12 permutations
So, 4 + 12 + 4 = 20 numbers have a sum of 3.
Both the District Of Columbia Lottery DC-4 '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 DC-4 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 DC-4 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 District Of Columbia DC-4 sum is expected to be drawn. For example, sums of 0 and 36 are expected every 10000 draws, while 17, 18 and 19 should show up every 15 draws.
A very late DC-4 sum will have its actual value very much greater than the expected value. Just as an eye-catcher,
we will show in blue those District Of Columbia DC-4 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.
