Which Lotto 6/49 numbers come up alongside 01 most often?
The number 01 has come up 508 times in 4,463 Lotto 6/49 draws, where chance predicts 546, and each of those draws handed it five partners. Its busiest partner is 44, beside it 69 times where chance predicts 57.
Every one of its 48 partners has turned up with it at least once, where chance predicts almost exactly none would still be waiting. Pick a different number in the box further down and every figure on this page follows it.
What was measured 15 couples per draw
A couple is two of the pool's numbers in no order. Draw 4463 was 011018212249, which holds 15 couples, so across 4,463 draws the record has drawn 66,945 of them counting repeats, against the 1,176 the pool allows.
One named couple sits inside one draw with probability 15 in 1,176, so the prediction for a partner is that near miss turned round and added up over the draws that could have held the couple. This game has drawn from one pool of 49 numbers throughout the record read here, so every couple has had the same chances. Each prediction is still summed over its own couple's run of draws, which stays right if the pool ever changes.
The record 48 partners of 01
Red marks a figure outside the range ordinary variation produces
The first figure is the one with a range: draws are independent of one another, so the count of draws holding 01 has an exact spread, and the partner slots beside it are that same count times five, which is the same reading said a second way rather than a new one. The last two count partners instead, and one draw lifts five 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 partner has a prediction of at least five appearances, so every row above is read against a range and 48 of them go into the comparison below. Every partner read here carries the same prediction, so ranking them by tally and ranking them by distance from that prediction come to one order, headed by 44 at +1.6 standard errors. Across the partners read here chance alone puts 3.1 of them that far out, so a leader of about that size is what a list of this length produces rather than a finding about 44. Outside the mark sit three partners, where chance predicts 2.2 would.
The same question, asked of the whole pool rather than one number. Of the 1,176 couples the pool allows, all of them carry a prediction of at least five appearances, and the one furthest above its prediction is 38and45, drawn together 82 times where chance predicts 57, or +3.3 standard errors. Reading that many couples, chance alone puts 1.1 of them that far out, so the top of such a long list is expected to look like this. Outside the mark sit 50 couples, where chance predicts 54 would. Neither of those two leaders is printed in red: both were picked out for being the highest of a long list, and a figure chosen for being extreme cannot also be evidence that something is going on. What the counts of marked rows are weighed against is the number chance alone puts outside the mark, which is given beside each of them.
Recent trend last 100 draws, then blocks of 20
How busy 01 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 13 times against a predicted 12, and the last 100 held it 14 times against 12. Chance predicts the same figure for both stretches, to the nearest tenth.
Share of draws holding 01, one point per block of 20 draws
result for the blockrange ordinary variation allowsoutside that range
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 ten blocks, chance alone puts 0.46 of them outside, so a point outside would not be explained by the number of blocks read.
