A probability and odds converter switches between probability (0–1 or %), fractional odds (a:b), decimal odds, and frequency (1 in n). All express the same likelihood differently.
सूत्र
Probability (0-1 or %) = favourable outcomes / total outcomes; Odds = probability / (1 − probability)
- P
- Probability (0 to 1 or 0-100%)
- O
- Odds (ratio (a:b or a/b))

अक्सर पूछे जाने वाले प्रश्न
What's the difference between probability and odds?
Probability = likelihood (0-1). Odds = ratio of likelihood. P=0.25 = odds 1:3.
If probability is 50%, what are the odds?
Odds are 1:1 (50/50). Same as even odds or "even money".
How do I convert odds to probability?
If odds are a:b, then probability = a / (a+b). Odds 2:3 = 2/(2+3) = 40%.
