Oregon Lottery Pick 4 Pairs Analysis

Oregon Lottery Pick 4 Pair Frequency and Last Appearance

The Oregon Lottery Pick 4 pairs analysis involves two sets of data. The first is the number of times a pair is drawn for the entire history of the game while the second set is how many draws have elapsed since a Pick 4 pair's last appearance. Whether pairs are included as a play type of the state's game or not, these analyses coupled with others, such as digits and sums analyses, will hopefully help you select the Pick 4 numbers to play.

The Analysis was performed on Sunday, May 19, 2013 with 9636 as the latest Oregon Pick 4 number. Just in case, the front pair of this number is 96, mid pair, 63, and back pair, 36.

Expected frequency of each Pick 4 pair is 171 (rounded to the closest integer).

Each Pick 4 pair, whether repeating or not, has equal chance of being drawn. Since we have 100 of each (front, back, and split), such pairs are expected to show up every 100 draws. We have shown in blue those Pick 4 pairs that have not been drawn between 200 and 300 draws (late pairs). And in red, those that have not been drawn in the last 300 or more draws(very late pairs)

There is also another method of pairs analysis which we haven't included here. It is "pairs at any position and any order", or in other words, "two numbers appearing together". For instance, 12 in 1020, 7219, 1062, etc. In fact, you can use our Oregon Pick 4 number search by entering "1-2-" to list all past Pick 4 draws that contain 1 and 2. In such type of pairs analysis, non-repeating pairs such as 12 have a better chance of being drawn than repeating, such as 11. In fact we do have this analysis for the current and previous months on our compact 2-month Oregon lottery page. Just select Pick 4 from the left bottom menu under "One Game", and then 'Pairs' from the top menu.
