1. Educational and informational purpose only

All calculators, simulators, and analyses on ProbLab are provided for general educational and informational purposes. They are not, and should not be relied upon as, professional advice in any domain — including but not limited to financial, investment, statistical consulting, medical, legal, or gambling advice.

2. No warranty of accuracy

While we make a good-faith effort to ensure calculations are mathematically correct, we provide all content "as is" and "as available", without warranty of any kind, express or implied. We do not warrant that the output of any calculator is accurate, complete, reliable, current, or error-free.

Nothing on this site is professional advice. In particular:

4. No "system" or "edge" claims

ProbLab does not claim that any tool gives users an "edge" in any game of chance, nor that any strategy we describe will produce long-term profit. All casino-game math shown (roulette, craps, blackjack, lottery) is published for educational purposes. House edges are mathematical realities, not opinions.

5. Age restriction

Tools relating to casino games (Craps, Roulette, Blackjack, Lottery) are intended for users 18 years or older (or the legal gambling age in your jurisdiction, whichever is higher). If you have a gambling problem, help is available at Gamblers Anonymous or the equivalent national helpline in your country.

Frequently asked questions

How do I use Disclaimer step by step without mistakes?
Follow the order given in the usage section: ProbLab provides educational and informational tools only. Outputs are not professional financial, medical, or gambling advice. See full disclaimer. The step-by-step part matters less than the unit check that sits inside it. Confirm every unit matches the thing you are actually trying to measure before you press calculate - that single check catches more wrong answers than any other habit, and it costs about ten seconds.
What are the common mistakes when using Disclaimer?
Most common mistakes come down to four habits: entering 20 when the field expects 0.2 because the field is a percentage; leaving a field blank and accepting the default without checking what it stands for; changing one input and reading a result that was calculated before the change; and quoting the output as an exact figure when the page describes it as a reference estimate. Press calculate again after any edit, and treat the number as a reference point rather than a final answer.
How do I read the result from Disclaimer?
Read the final figure first, then come back to this section for the conditions behind it: ProbLab provides educational and informational tools only. Outputs are not professional financial, medical, or gambling advice. See full disclaimer. Keep two things apart: the number itself, which comes from the values you typed, and the assumptions it depends on, which decide whether that number is meaningful. The page sets out what a higher or lower result means for your case, so check that direction as well as the magnitude.
Can I act on the Disclaimer result directly?
Treat it as one reference sheet before you decide, rather than as the answer itself: ProbLab provides educational and informational tools only. Outputs are not professional financial, medical, or gambling advice. See full disclaimer. The output describes a magnitude under the conditions you entered. It does not include what it actually costs to act, what might change while you act, or how the other side behaves. Before you commit, compare the result against reality and note which assumptions do not hold where you are.
