Question

The probability of E is 11% find the odds against (E)

Answer 1

well, we can calculate odds from probability using a simple formula

`p=(o)/(o+1)`

where p = probability

o = odds

`o=(p)/(1-p)`

let's substitute the values into the equation

note: 11% = 11/100

`\begin{gathered} o=((11)/(100))/(1-(11)/(100)) \\ o=((11)/(100))/((89)/(100)) \\ o=(0.11)/(0.89) \\ o=0.124\text{ } \\ o=(11)/(89)\text{ when you multiply the fraction by 100} \end{gathered}`

the odds is 11/89 or 0.124
