フィッシャーの正確確率検定（直接確率）
周辺度数 $e$，$f$，$g$，$h$ を固定した分割表は複数個考えられるが，観察された分割表が得られる確率は次式のようになる。 $P_{a} = \displaystyle \frac{{}_{e}C_{a} \times {}_{f}C_{c}} {{}_{n}C_{g}} = \frac{e!\ f!\ g!\ h!} {n!\ a!\ b!\ c!\ d!}$ これを，例題で説明しよう。 まず，“甘いものが好き”な $17$ 人から $13$ 人を取り出す取り出し方は， ${}_{17}C_{13} = 2380$ 通りある。 同様に，“甘いものが嫌い”な $20$ 人から $6$ 人を取り出す取り出し方は， ${}_{20}C_{6} = 38760$ 通りある。 帰無仮説が正しいとすると「“甘いものが好きか嫌いか”と“虫歯があるかないか”は“独立事象”なので，“甘いものが好き
