flopToTurnAtLeastOneHitProbability

One-street flop→turn hit: outs/unseen.

flopToTurnAtLeastOneHitProbability(outs: number, unseenAfterFlop: number): number

Import

const poker = require('poker-calculations');

ESM (Node):

import { createRequire } from 'module';
const require = createRequire(import.meta.url);
const poker = require('poker-calculations');

When to use

One card to come on the flop (turn only). Same hypergeometric rate as hypergeometricOneCardHitProbability but named for the flop→turn street.

How to use

const outs = 9;
const unseen = 47; // deck after flop (2 hole + 3 flop)

const pTurn = poker.flopToTurnAtLeastOneHitProbability(outs, unseen);
console.log(pTurn); // 9/47 ≈ 0.191

// Compare to full flop→river two-card draw
console.log(poker.flopToRiverAtLeastOneHitProbability(outs, unseen));
