, this is calculated by taking one of the 52 cards from the stock pile and then another of the remaining 51 cards :
(1/52) * (1/51) = 1326 combinations .
If we ignore the different combinations of color, then this number can be reduced to 169 different starting hands . Of which 13 are pairs , 78 are letters different but the same color, and the remaining 78 are unpaired cards and a different color .
The cards you are dealt affect the likelihood that your opponent has similar letters . For example if you get an ace preflop then are only 3 remaining aces in the maso . So the odds that your opponent receives an ace fell by 25 % .
The table below shows the probability that you are dealt a certain strength before the flop :
A- A ( 220/1 or 0.45 %)
A- K (81.9 / 1 or 1.1 %)
A- A, K -K, Q or Q- 10-10 (54.3 / 1 or 1.8 %)
Any initial torque ( 16:1 or 6.25 % )
Any two cards with J or higher ( 10.1 / 1 or 9.05 % )
