How do you find odds in favor and odds against?
determine the number of winning outcomes and losing outcomes then divide each by the total number of outcomes.
If there are 4 chances of winning and 10 possible outcomes then the odds of winning are 4/10 or 2/4
If there are 5 chances of winning and 10 possible outcomes then the odd of losing are 5/10 = 1/2
It is possible that some outcomes are neutral and do not result in either winning or losing In this example 1/10
