In tennis, the outcome of a match can be modelled by first estimating the probability of a player winning an individual set. This set‑win probability depends on the player’s ability to win points on serve and on return, and can be derived from Markov‑chain models of games and tie‑breaks.
Once the set probability (denoted (P_{set})) is known, the match probability follows a binomial distribution because a match is essentially a series of independent set outcomes. For a best‑of‑3 match the player must win two sets, while a best‑of‑5 match requires three set wins.
The calculator below uses these principles to convert a user‑provided set‑win probability into an overall match‑win probability for the chosen format.
