2-7 vs. A A

In a ten handed game what are the odds of someone being dealt 2-7 and beating pocket A A at the showdown? Suits dont matter.

Also what are the odds of being dealt 2-7 and beating pocket J J or better?

Im looking for a 1 in ****** answer. Im not assuming both players already have those hands

Pre flop the AA is about a 86% favorite. Since AA will often raise pre flop it is even less likely that 7,2 will be played though. If you're asking how often AA will be dealt in the same round as another player is dealt 7,2 and the 7,2 player actually plays their hand to the river--well then you would have to have a very very weak player who loves to bluff off his money playing long shots. 7,2 would have to hit trips or two pair on the flop to make continuing worthwhile.
