Descriptive statistical analysis
Same probability.
Different share.
Analyse only numbers you enter yourself. Memoryless Lab shows exact probabilities and, separately, an educational prize-sharing scenario; it never generates, completes or recommends combinations.

Visible mathematics from the start
Six measures. Verifiable formulas, not labels.
Before input, the full method is visible; after analysis, every row shows the formula, result and descriptive reading.
Sum, mean and deviation
Observed sum, 95% band and approximate normal percentile.
S = Σxᵢ · z = (S − μ) / σResult after analysisNo number is generated or prefilled.
Consecutive pairs
Observed count, combinatorial expectation and probability of at least one pair.
A = Σ 1(xᵢ₊₁ − xᵢ = 1) · E[A] = k(k−1)/MResult after analysisNo number is generated or prefilled.
Even and odd split
The theoretical frequency of the entered even/odd structure.
P(E=e) = C(E,e) × C(O,k−e) / C(M,k)Result after analysisNo number is generated or prefilled.
Set dispersion
Observed range, expected value and deviation from expectation.
R = max(x) − min(x) · E[R] = (k−1)(M+1)/(k+1)Result after analysisNo number is generated or prefilled.
Combinatorial information
Bits required to identify one outcome in the complete outcome space.
I = log₂(1/p) = log₂(Ω)Result after analysisNo number is generated or prefilled.

Even / odd structure
—P(E = e)
P(E=e) = C(45,e) C(45,6−e) / C(90,6)Sector area is proportional to the exact probability. The white sector marks the observed even count.
Range distribution
R = —E[R] = 65
P(R=r) = (90−r) C(r−1,4) / C(90,6)Each point gives the exact probability of a distance between minimum and maximum. White: observed value. Coral: theoretical mean.

Appearances
Number
Binomial reference with Bonferroni correction across all displayed numbers. Under uniform, independent draws, coverage is at least 95% for one sample fixed in advance. Searching across different sample windows is exploratory; an outside point does not establish a biased draw.
Main numbers only; bonus numbers are excluded. Historical differences do not change the probability of the next draw.
Frequencies and historical absence describe only the selected sample; they do not change the probability of the next draw.
The complete mathematical profile is free during the public beta.
