What is the odds against an event happening when the probability of an event happening are 71%? ___________

Solution

Odd against of a event=(Prob. of Losing)/(Prob. of Winning) = (1-P)/P

where P is Prob of happening = 71% = 0.71

then Odd against of a event = (1-0.71)/0.71 = 0.29/0.71 = 0.4084

hence Odd against of a event = 40.84%
