Which Mega Millions numbers come up alongside 14 most often?

A couple is two of the pool's numbers in no order. Draw 163 was 1419214567, which holds ten couples, so across 163 draws the record has drawn 1,630 of them counting repeats, against the 2,415 the pool allows.

The first figure is the one with a range: draws are independent of one another, so the count of draws holding 14 has an exact spread, and the partner slots beside it are that same count times four, which is the same reading said a second way rather than a new one. The last two count partners instead, and one draw lifts four of those couples at once, so their spread would need the covariance between couples that share a number. That is not honestly available, so those two carry predictions and no range, and nothing in this section is in red beyond the first figure and the table.

Every row above is marked thin. Chance predicts fewer than five appearances for each of these couples, which is too few for a range to mean anything, so none of them is given one and there is nothing here to rank. A longer record, or a game that draws more numbers at a time, would change that.

How busy 14 has been lately is how many partner slots it has been handing out, so this is the one figure the rest of the page rests on. The first 100 draws it could appear in held it seven times against a predicted 7.1, and the last 100 held it three times against 7.1. Chance predicts the same figure for both stretches, to the nearest tenth.

Oldest block on the left, newest on the right. The band is what chance predicts for those same draws, worked out from each draw's own pool. No point sits outside the band. Across eight blocks, chance alone puts 0.36 of them outside, so a point outside would not be explained by the number of blocks read.
