This may be a very stupid question but theres a lot of people here that could answer it.lets say the cs go opening case for example,if there was a 1 in 10 chance of me getting a purple ranked weapon then the probability would be 1 in 10 right? And if there was a 1 in 10 chance of me getting the purple ranked weapon stat trak then would I do 10x10 which is 100, so does that mean I would have a 1 in 100 chance of getting a stat trak purple?

If there are two die rolls and you need both, you multiply them together. 1/10 * 1/10 = 1/100 chance of getting both.

It actually more than 1/10https://www.reddit.com/r/GlobalOffensive/comments/228117/new_2000_case_opening_studyhttp://steamcommunity.com/app/730/discussions/0/864977564519711748/
