What are the chances of losing a giveaway?

The number of entries minus one (this one is the winning chance instead).

random fact: going to gym prevents obesity.

Probably 99.99%

I'm not even joking

Inversely proportional to the chance of winning

50%...you either win or lose :D

1 - chance of winning, i think

I'd say equal to the amount of giveaways you enter ofcourse

1 - result from http://www.steamgifts.com/forum/QiTxM/what-are-the-chances-of-winning-a-giveaway :P

42

About the same as seeing another "I haven't won, yet" thread pop up. Highly likely.

For you? 100%. For everyone else, 0%

The chances of losing a giveaway are slightly higher than the chances to lose a comment.
