The probability of the sampling without replacement scheme can be computed analytically. Let z be an ordered sample without replacement from the indices { 1, …, n } of size 0 < k ≤ n. Borrowing Python notation, let z: t denote the indices up to, but not including, t. The probability of z is. P r ( z) = ∏ t = 1 k p ( z t ∣ z: t ...
