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

Answer

A 1% chance is

1 in 100

On average once per 100 tries — not a guarantee: tries are independent. As odds it is 1 to 99 (1 for, 99 against).

Chance it happens at least once
chance		tries
50%		by try 69
≈ 63.4%		100 tries (= X)
90%		by try 230
95%		by try 299
99%		by try 459

1% = 1 ÷ 100 = 0.01; X = 1 ÷ 0.01 = 100
