The formula behind the result
The formula operates on the values exactly as entered; keeping the units shown in each label is what makes the probability trustworthy.
Worked example: with cards of the same suit needed of 5, this poker flush odds calculation returns Probability: 0.1981%. The same run reports 1 in 505 hands | Ways: 5,148 of 2,598,960 | A 5-card flush includes straight flushes — subtract 40 ways to exclude them.
The steps it follows:
- Formula: P = (suit choices × suit-card picks × other-suit fill) ÷ C(52,5)
- Ways = C(4,1) × C(13,5) × C(39,0) = 5,148
- Total 5-card hands = C(52,5) = 2,598,960
- P = 0.1981% ≈ 1 in 505
Substitute your own values and the same steps produce your answer — that is the point of a calculator that shows its working.
