| BaldrSkies said: The chances of getting p, s, and 4 lined up in order in a Youtube URL on a particular video is beyond miniscule. Not only that but it's separated by a dash and is placed at the very end. Pretty sure it's because Google hates Microsoft. |
The probability of getting ps4 in that order (not caring about capitalisation - ps4, pS4, Ps4, and PS4 all counting) in the URL, assuming that all of them have 11 randomly chosen characters from the set {a-z, A-Z, 0-9, _, -} (that's 64 character possibilities), can be worked out without too much trouble, and isn't as small as you'd think.
To make the point, let's consider the probability that the URL finishes with either underscore or dash, followed by any capitalisation of "ps4". That's a one in 2097152 chance, for that very specific case. Sounds tiny, until you realise that 120 million videos have been recognised by Youtube's Content ID system... which means, given that most videos won't have copyrighted content, that the total number is easily in the billions.
The probability that the sequence "ps4" appears somewhere in the URL is in the vicinity of 0.01%, or a one in 10,000 chance (it's actually more likely than that, I'm rounding down the probability). That's not even remotely "beyond miniscule".
