How many chests to open to have a knife

One, if you are lucky enough.

about 1 in 384 you can boost your luck if you have a new account and you buy keys from the marketplace but seriously dont open cases

[Skipspik]

it's a bernouilli experiment with P=0.0026, a =1, and we don't care about b so just put a high number something and check P(X)>= 1

Worth noting that after 900 case you still almost have 10% chance of not having one.
However, you pass the 75% treshold of getting at least one around 400-450

I don't have much money

[MARCIN44R4]

its completely random some people gets knife in thier first open but its rare and extremely lucky and dont believe people that say new account have more chance to get knife cuz its f bulls.hit

[GlawGlack]

you roll the dice every time

the chance doesn't accumulate

ex. 0.01% for every case, not 0.01% -> 0.05% -> 1%

Chances don't really stack up, could be everything. It usually is a lot tho. Some get luckier than others.

If you don't have enough money to buy a knife, you definitely don't have enough money to open cases for a knife.

There is no way to "boost your luck." Skipspik's answer gives the mathematics. If you want to simulate the experience of opening cases without risk, look at

with whatever case you were going to try.

Opening many cases is best left to people who can afford it: wealthy people, streamers and YouTubers who generate income from people watching the openings, and so forth. Most of us only open a few cases here or there if we have a little extra money in our Steam account, or not at all.
