    FAQ

    How do you turn a percentage into a "1 in X" chance?

    Divide 100 by the percentage: a 25% chance is 100 ÷ 25 = 1 in 4, and a 5% chance is 100 ÷ 5 = 1 in 20. The same rule written as a formula is 1 ÷ (percent ÷ 100).

    Is "1 in 5" the same as odds of "1 to 5"?

    No. "1 in 5" counts one favourable outcome among five outcomes in total, which is 20%. Odds of "1 to 5" compare one favourable outcome against five unfavourable ones — six in total — which is 16.67%.

    Does a 1 in 10 chance mean the event happens once in every 10 tries?

    No, the tries are independent and nothing guarantees a hit. Over 10 tries the probability of at least one hit is 1 − 0.9^10 ≈ 65%, so roughly 35% of such runs end with no hit at all.
