Chances of winning the lottery :
What are the chances of matching k numbers out of n numbers from a set
of m numbers ?
The number of combinations of k from n
Multiplied by
The number of combinations of nk from mn
divided by
The number of combinations of n from m
In closed form, this can be represented as ^{n}C_{k}
* ^{m}^{}^{n}C_{n}_{}_{k} / ^{m}C_{n}
where ^{x}C_{y}
= x! / [y! (xy)!], “x choose y”
where x! = factorial x, the
product of all integers from 1 to x.
Poker odds :
The total number of unordered combinations of 5 cards from a 52 card
set is ^{52}C_{5} = (52*51*50*49*48) / (5*4*3*2*1) = 2598960.
To obtain the odds for each winning hand, we count the number of possible hands
and divide it by this figure. We can count by considering suits (4) in
combination with values Ace to King (13).
Royal Flush: we simply have 4 possible suits, so the odds are 4 / 2598960
= 0.000001539
Straight Flush: we can have one of 4 possible suits, starting with 1
(Ace) up to 9 (flush starting with 10 is a Royal Flush so is not counted), so
the odds are 36 / 2598960 = 0.00001385
Four of a Kind: the four can have one of 13 values, with the fifth card
being any one of the 48 other cards. The fifth card can alternatively be
considered to be any one of 12 values of 4 suits. Either way, we have 13*48 =
624 / 2598960 = 0.000240096
Full House: the triple can have one of 13 values, with any 3 from 4
suits (^{4}C_{3} = 4) , and the pair
can have one of 12 remaining values, with any 2 from 4 suits (^{4}C_{2}
= 6). This gives 13*4*12*6 = 3744 / 2598960 = 0.001440576
Flush: we can have one of 4 possible suits and any 5 from 13 values (^{13}C_{5}
= 1287), excepting straight flushes (of which there are 40), so the odd are
4*1287 − 40 = 5108 / 2598060 = 0.0019654
Straight: we can have one of 10 possible starting values, with each
card of any suit (4^{5}), excepting straight flushes, so the odds are
10*4^{5} − 40 = 10200 / 2598960 = 0.003924647
Three of a Kind: the three can have one of 13 values, with any 3 from 4
suits, the fourth card can be any one of 48 with different value, the fifth card can be any one of 44 with different value
again, dividing by 2 to disregard order. Alternatively, the fourth and fifth
cards can be viewed as any 2 from 12 values, of any suit. Either way we have
13*4*12*11*4^{2} / 2 = 54912 / 2598960 = 0.02112845
Two Pair: we can have one of 13 values for first pair, any 2 from 4
suits, any one of 12 values for second pair, also any 2 of 4 suits, dividing by
2 to disregard order of pairs, and the fifth card can be any of remaining 44
cards (11 values, 4 suits). The odds are then 13*6*12*6*44 / 2 = 123552 /
2598960 = 0.047539
Pair: we can have one of 13 values for the pair, any 2 from 4 suits. He
other cards must all have different values, so any from 48, then 44, then 40,
divided by 3! = 6 to disregard order. Alternatively, the other cards can be
considered any 3 from 12 values, of any suit. Either way we have
13*6*12*11*10*4^{3} / 6 = 1098240 / 2598960 = 0.422569
No hand: the sum of the above subtracted from the total is 2598960
− 1296420 = 1302540 / 2598960 = 0.5011774. Alternatively, we can consider
any 5 different values from 13 values, excepting the 10 straights, each card of
any suit, excepting the 4 flushes, to get (^{13}C_{5} −
10)*(4^{5} − 4) = 1277*1020 = 1302540, as expected.
Ace High: Given that the first card is an Ace, we require any 4 from 12
values excepting straights that would create 5card straights with an Ace, of
which there are 2 (considering Ace High or Ace Low). Each of the 5 cards can be
of any suit, excepting the 4 flushes, as above. The odds are therefore (^{12}C_{4}
− 2)*(4^{5} − 4) = 493*1020 = 502860 / 2598960 = 0.193485,
which is a surprisingly high percentage of all no hands.
The method for Ace High can be used for lower Highcard hands, as
follows
King High = (^{11}C_{4} − 1)*(4^{5}
− 4) = 329*1020 = 335580 as there are 11 lower cards
Queen High = (^{10}C_{4} − 1)*(4^{5}
− 4) = 209*1020 = 213180
Jack High = (^{9}C_{4} − 1)*(4^{5}
− 4) = 125*1020 = 127500
Ten High = (^{8}C_{4} − 1)*(4^{5} −
4) = 69*1020 = 70380
Nine High = (^{7}C_{4} − 1)*(4^{5}
− 4) = 34*1020 = 34680
Eight High = (^{6}C_{4} − 1)*(4^{5}
− 4) = 14*1020 = 14280
Seven High = (^{5}C_{4} − 1)*(4^{5}
− 4) = 4*1020
= 4080
The numbers 493, 329, 209, 125, 69, 34, 14 & 4 add up to the 1277
combinations allowed in a Nohand, so Six High is impossible by exclusion. On
the other hand, Six High is logically impossible anyway since the only set of
four different values all less than a six creates a straight, which is also
ruled out.
Note that Highcard hands are all individually less likely than a Pair,
though they add up to just over 50% of all 5card hands.
