The model uses entered outs and unseen cards to calculate the chance of a hit on one draw or across two draws. It assumes the inputs are accurate and does not infer hidden cards or player behaviour.
With nine outs and 47 unseen cards, the one-card chance is about 19.15%. The two-card chance is higher because the model gives two opportunities to hit.
