User blog comment:ReddUT/How to calculate probability of obtaining something you want from Top 50 decoders./@comment-31412431-20170717050725

One thing we need to figure out is that, If the ramdom seed changes when we open up decoders. If you don't know what is a random seed, see this .

If so, your thing doesn't do anything as the seed isn't the same each time, so the chance is 1% forever.

If not so, your calculation may be a reference.

In my experience of opening Decoders and things like it (Dota 2 treasures, CS:GO boxes, etc.), the seed doesn't change and your claim makes sense. However, we can't confirm that.

Either way, just pay.
