Question 33621
If it has been determined that the probability of an earthquake occurring on a certain day in a certain area is 0.03125, what are the odds AGAINST an earthquake? 
ODDS IN FAVOUR =0.03125
ODDS AGAINST =1-0.03125=0.96875
ODDS AGAINST/ODDS IN FAVOUR =0.96875/0.03125=96875/3125=19375/625=3875/125
=775/25=155/5=31/1
