if there are 4 dismonds on the board?

[PokerTony]

if there are 4 diamonds on the board? And there is only 1 other person in the hand, what are odds that other person has atleast 1 diamond in his hand?

[gametime74]

due the math ..total number of cards plus total number of players on table plus total amount of diamonds in the deck..try it out..lol

You know 7 cards. Your 2 and the 5 on the board. (The number of other players does not change this.) There are 45 other cards and 9 are Diamonds. 1 in 5 is 20%. He has 2 cards so 2 in 5 is 40%

Of course the action of the hand should give you some idea of what he might have. Did he play like he was on a draw? Was he agressive until the 4th Diamond hit. Is he a bluffer or trapper? That should tell you more than worrying about pot odds.

It's 50/50. Either he does or he doesn't. Ha Ha Ha... Sorry, little punchy, just got runner runnerred to lose a tournament AJo > QQ with a Q on the flop. It all went in post flop too... +1 to mawoyto

13 Diamonds in a deck, minus 4 on the table, equals 9 outs.
9 outs out of 52 cards in a deck, Minus the 7 cards that are already seen by you ( 5 on table, 2 Hole )
9/45 = 20%

So basically, about 1/5

All this is assuming you do not hold one in your hands as well.

Edit : As posted while I was posting is right ! I forgot to double up considering he has 2 cards.

40% is right.

You've definitely gotten the math answer to your question but it comes down to this, how did your opponent play the hand. More information is needed.

[chrisdione]

it is not only this hand but other hands as well factor into this decision. there was a lot of info left out of the question for a solid answer but they supply you with the math you needed.
