The frequency most typical of a fair drum (highest Bernoulli probability) in Рапидо Старт belongs to the numbers (sample: 20): Field 1: 11 (7.21%), 17 (7.21%), 1 (6.65%), 15 (6.65%), 18 (6.65%), 20 (6.65%), 2 (6.41%), 19 (6.41%). Field 2: 1 (27.18%).Data includes draw #182570 of 10.07.2026.
A high coefficient means a number came up roughly as often as a uniform drum would predict — its frequency is statistically “normal”. It does NOT mean the number is more likely to be drawn next: the draw is random and all combinations are equally likely. The method is a distribution diagnostic, but as a selection system it works: clicking a number in the table adds it to the combination generator.
The Bernoulli formula gives the probability that a number is drawn exactly k times in n draws under a uniform chance p. The table shows this probability, normalised to %. Nearby, related views of the same frequency: Frequency →Z-Score →
P(k) = C(n, k) · pᵏ · (1 − p)ⁿ⁻ᵏ
where for each number:
- k — how many times the number was drawn over n draws; n — the number of draws;
- p — the chance of the number being drawn in one draw = (numbers per draw) / (balls in the drum);
- in the table each number is shown as the share of its probability P among all numbers (%).

OpenFrequently asked questions about Рапидо Старт
What is the Bernoulli formula for the Рапидо Старт lottery?
It is the binomial probability formula: it estimates how likely it is that a number was drawn exactly k times in n draws under a uniform chance p. So for each Рапидо Старт number you can see how typical its observed frequency is for a fair drum.
What does a high coefficient for a number mean?
That its draw frequency in Рапидо Старт is close to what a uniform drum would expect — statistically “normal”. A low coefficient marks numbers with an anomalous frequency (very frequent or very rare). This describes the past, not a forecast.
Should I play Рапидо Старт numbers with a high coefficient?
The coefficient gives no future advantage — the draw is random and all combinations are equally likely; the Bernoulli formula cannot guarantee or increase the chance of winning. But if you want to pick numbers by a system rather than at random, use the method as a selection basis and the generator built on it.
How do I compute the odds of winning, of matching N of M?
That is a different question — the combinatorial probability of a match, not the frequency of individual numbers. The chance of matching the required number of hits in Рапидо Старт is on the “Winning odds” page.
