Estimate
A four-leaf white clover
- Probability:
- 0.0197%
- Odds:
- 1 to 5,080
- dBan
- −37.1 dBan
The cited estimate finds one white clover with four leaflets for every 5,076 with three. Among those three- and four-leaf clovers, that is one in 5,077.
Calculation
p ≈ 1 / (5,076 + 1) = 1 / 5,077
Assumptions
The comparison is restricted to three- or four-leaf white clovers. It is an approximate occurrence estimate rather than a precise worldwide survey. Genetics, environment, and the clover patch can change the rate. Search method, time, and patch choice determine the chance of finding one during a search.
