texas holdem probability question

I don’t under stand why this question is so hard. Me and my opponent go all in preflop. I have the ace of hearts and the king of spades. My opponent has the ace of spades and the king of hearts. What is the probability that we won’t split the pot?

According to this Texas Holdem Calculator, and assuming 48 live cards, Each player has 0.74% or winning the hand and a 98.52% chance of splitting the pot.

reported for a forum change to game room.

Wouldn’t the only way to not split the pot be if four or five of the flop, turn, and river cards are spades, or four or five are hearts?

I don’t understand. 98.52% + 0.74% does not equal 100%. What are the other outcomes?

But 98.52% + 0.74% + 0.74% = 100%

EACH player has a 0.74% chance of winning.

98.52% split pot
.74% you win
.74% opponent wins

This totals 100%.

In other words, the probability is 0.0148 (1.48%).

No need. The question has been answer. May as well just close it.

Not sure which probability calculator Mensa used—there are several—but I just wanted to chime in with one of my favorite pieces of freeware: Pokerstove.

There are more powerful equity calculators out there, but I think you have to pay for them. With Stove, it’s easy to figure out ranges and odds of winning/splitting for a variety of ranges; both your own and as many as 9 different opponents. It can’t do Bayesian weights for elements within the range, but that’s really a small quibble.

Now if I could just find a version of it for Omaha…

I used the one at cardplayer.com. I thought I inserted a hyperlink, but apparently not.

Assuming no other player is in the pot, yes.
