1 in 100 Chance?
I was browsing the forums of World of Warcraft, and it was mentioned in a thread there that the drop rate of something was 1 in 100. Someone was asking, why is it that, after 100 times going for this item 100 times, I still don't have it? Well, i thought the answer was obvious, that as it's on an Random Number Generator then its a different roll each time, and theres just a higher chance it will roll what you want and the item will drop. However, this other person said,
Quote: "You don't know probability. If you run something 100 times with a 1 in 100 chance, that only equates to a ~63% chance it will drop.".
Can someone please explain to me how this works?
