Pennsylvania Lottery Big 4 Pairs Analysis

Pennsylvania Lottery Big 4 Pair Frequency and Last Appearance

The Pennsylvania Lottery Big 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 Big 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 Big 4 numbers to play.

The Analysis was performed on Sunday, May 19, 2013 with 5388 as the latest Pennsylvania Big 4 number. Just in case, the front pair of this number is 53, mid pair, 38, and back pair, 88.

Expected frequency of each Big 4 pair is 138 (rounded to the closest integer).

Each Big 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 Big 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 Pennsylvania Big 4 number search by entering "1-2-" to list all past Big 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 Pennsylvania lottery page. Just select Big 4 from the left bottom menu under "One Game", and then 'Pairs' from the top menu.
