If 5/14 Is the probability of occurrence of an event, find (i) the odds in favor of its occurrence (ii) the odds against its occurrence |
Answer» (i) We know that, If odds in favor of the occurrence an event are a:b, then the probability of an event to occur is \(\frac{a}{a+b}\) Given, probability = \(\frac{5}{14}\) We know, probability = \(\frac{a}{a+b}\) So, \(\frac{a}{a+b}\) = \(\frac{5}{14}\) a = 5 and a+b = 14 i.e. b = 9 odds in favor of its occurrence = a:b = 5:9 Conclusion: Odds in favor of its occurrence is 5:9 (ii) As we solved in part (i), a = 5 and b = 9 As we know, odds against its occurrence is b:a = 9:5 Conclusion: Odds against its occurrence is 9:5 |
