odds of being dealt a pair in holdem is 1 in 17. 13 pairs so 13/221 times you will get a pocket pair. speaking of an individual pair is 1 in 221. so taking 4 pocket pairs and string them in a row the odds are:
[(1/221)*(1/221)*(1/221)*(1/221)]*[1/256] = tiny ass number.
the first part is the odds of being dealt those 4 big pps all in row. and roughly you are 4:1 to win the overpair vs underpair, so (1/4)^4 = 1/256 which is where you get the second number. essentially, it shouldnt happen, but in rare instances when you have bad karma coming to you, it does happen. |
