SUMMARY

On July 14th, 2025, a bridge player was dealt two 13-card hands in a single session where the highest card was a seven, an event calculated to have a probability of approximately 1 in 234 million. This statistic highlights the rarity of such occurrences in bridge, a card game that involves complex probability calculations. The discussion reflects varying opinions on the precision of this probability, with some participants suggesting that a rough estimate suffices. The conversation also references a Wikipedia article on "Go and Mathematics," which discusses similarly astonishing probabilities.

I admit I'm not into bridge but the comments to the OP you linked to makes it look pretty confusing. At least for someone like me who don't really get the game...

EDIT: I mean they don't seem to agree...

EDIT2: Oh, overlooked this one:

"
I got 1 in 234,484,904.

I think we can all agree that it's approximately 1 in 234 million. Do we really need to worry about being more precise?
"

Pretty wild, I'll admit.
 
There's a "Go and Mathematics" article on Wikipedia which also "sports" some pretty wild numbers.
