Question

Find the odds in favor of his character unlocking the treasure chest

Answer 1

First, we are given the probability of unlocking the treasure chest

`p=(9)/(20)`

To find the odd, we

`\begin{gathered} Favourable\text{ Event = 9} \\ \\ Unfavorable\text{ Event = }20-9 \\ \\ Unfavorable\text{ Event =}11 \end{gathered}`

So the answer is

`Odd=(9)/(11)`
