What is 25% chance as a 1 in X probability?

Answer

A 25% chance is

1 in 4

On average once per 4 tries — not a guarantee: tries are independent. As odds it is 1 to 3 (1 for, 3 against).

Chance it happens at least once
chance		tries
50%		by try 3
≈ 68.4%		4 tries (= X)
90%		by try 9
95%		by try 11
99%		by try 17

25% = 25 ÷ 100 = 0.25; X = 1 ÷ 0.25 = 4
