What are the odds of this to happen!

[primrose1234]

First hand: 10 of hearts 9 of diamonds
Second hand: 10 of hearts 9 of diamonds
Third and last hand: 10 of hearts 8 of hearts.

Three times the 10 of hearts, twice the 9 of diamonds, very similar hands in general!

The odds of the same card in your hand two hands in a row is 1/26. The odds of the same card in your hand three hands in a row is 1/26 * 1/52 or 1 in 1000. Not that unlikely if you play a lot.

1st hand: I assume you don't care specifically about what cards you get, then any combo will do.
2nd hand: To get the exact same cards again (I guess you don't care about the order): 1/26 * 1/51 = less than 0.1% (1 in 1326)
3rd hand: Same as above for it to happen, less than 0.001% (~ 1 in 1.7 Million)

Now if you allow for the 3rd card a variation of ±1 for one of the cards, it's ~0.3% and combined ~0.00025% (~ 1 in 400'000)

If you got the same pocket pair two hands in a row, and then another pocket pair on the third hand, would you have posted here? If you got Ah suited 3 hands in a row, would you have posted here? There are lots of possible combinations that would be "post worthy", but when you add them all up, the odds are reasonable you will have one of them.
