Probability tools are for learning.

ToolMitra explains combinations, probability, expected value and risk. It does not provide predictions, tips or a way to place a wager.

What these tools do

Lottery, game and risk calculators show how stated assumptions affect mathematical outcomes. They can illustrate why an expected result may be negative, how rare an outcome is, or how a payout structure changes a calculation.

Advertising exclusion

Matka, lottery, betting, casino and wagering-promotion mathematics pages are permanently excluded from ToolMitra advertising. The site has no active advertising today, and the central advertising component will not load an ad-serving script on these routes if advertising is introduced elsewhere.

What these tools do not do

They do not select numbers, forecast draws, analyse historical results as a prediction system, recommend stakes, accept payments, place bets or direct visitors to bookmakers, casinos, lottery sellers or unregulated operators.

Use assumptions carefully

Odds, prize tiers, taxes, fees, availability and legal status vary by product and jurisdiction and can change. Check official terms and applicable local law independently. A calculation is not legal, financial or gambling advice.

If gambling is causing harm

Stop using the tool for wagering decisions and seek support from an appropriate local health, financial or gambling-harm service. If you are in immediate danger, contact local emergency services.

Our content standard

We describe the underlying mathematics and its limits. We do not publish “guaranteed win” claims, betting strategies presented as certain, number-picking systems or affiliate links to gambling operators. See our approach for the wider product standard.
