No, again 168 is the total. So if you take 168-117(Which is the odds for winning) you get 51. So your odds against winning are 51/168

okay, but my only options to choose from are:

117:168

117:285

168:285

168:117

Odds....I hate teaching that.

If in a contest, 3 people can win, and 5 loose, the probablility of winning is 3/8

The odds are stated to be 3:5

It is a crazy system. Bet on a horse 1:1, and you have .5 probabliltiy of winning.

So here, 117 winners, 168 loosers, so the probability of loosing is 168/(168+117), and the odds of loosing is 168:117

Nuts to the math of odds.
