Stupid question about burn cards...

I understand they're used to deter card marking and such. But I was wondering if they add to the randomness at all. Like I said, stupid question. But I really am curious and not nearly good enough at math to figure it out on my own.

They do not in anyway affect the percentages of certain events occuring as they are unknown cards, now if they for some reason become known then you can account for them and adjust calculations accordingly; just the same as if you found out what your opponents hole cards are.

Thanks . I knew it was a dumb question but I still needed the answer.
