odds question

[RemyXO]

This is just a conversion from odds to probability in percentages.

To convert odds to probability, you have to add the chances. So, if the odds against you winning are 2.22 to 1, this means that out of 3.22 (2.22 + 1) chances, you have 1 chance of winning. So the probability is thus 1/3.22 = 0.3106 or 100%/3.22 = 31.06%
