The addition of a joker to the ordinary
52-card deck makes for some slight adjustment in the total number
of hands, their frequencies and the odds. The following table
shows the changes (compare with table on page 114). There are
now 2,869,685 possible hands:
The interesting fact revealed by this table, aside from the increased
frequency of almost all hands (except hands less than one pair,
which remain the same) and the addition of a new hand, five of
a kind, is that three of a kind, formerly scarcer than two pairs,
is now more frequent. This makes two pairs an even less likely
winning hand than in Five-Card Stud or Draw Poker without the
joker.
Although giving the 4 deuces
special powers does not change the total number of hands possible,
it does drastically alter the order and frequency of the hands.
Compare the following table with those on pages 114 and 123:
This table also reveals some interesting realignments: Five of
a kind is much more difficult to get than a straight flush and
accordingly ranks above it. Four of a kind is more common than
either a flush or a straight and more common than the frequency
of both together. Three of a kind will occur almost four times
as frequently as two pairs, making it understandably the
playable hand.
