What are the Odds of A Paired Board on the Flop

[biohazard]

I have recently been playing 6 max tables at party poker and have noticed that the board has been paired 336 JJ7 QQ7 or the like at least 1 in five times if not more at some points in the game. I have ben playing online for about 4yrs and this stuck out to me as I was playing so I was wondering if someone has either noticed the same thing or if this probability is normal. Thanks

You are an idiot.

You are an idiot.

That's not very nice

Over a very large sample, it is probable that you will see the "improbable" very often. That's what this sounds like
