# Question: Let X 1 X 2 X n

Let X(1) ≤ X(2) ≤ . . . ≤ X(n) be the ordered values of n independent uniform (0, 1) random variables.

Prove that for 1 ≤ k ≤ n + 1,

P{X(k) − X(k−1) > t} = (1 − t)n

where X(0) ≡ 0, X(n+1) ≡ t.

Prove that for 1 ≤ k ≤ n + 1,

P{X(k) − X(k−1) > t} = (1 − t)n

where X(0) ≡ 0, X(n+1) ≡ t.
