If an event has a probability of "A", then the complementary event will have a probability of "1 - A".

Given, the probability of an event is 9/25, we can easily find the probability of the complementary event. Shown below:


\begin{gathered} 1-(9)/(25) \\ =(25)/(25)-(9)/(25) \\ =(16)/(25) \end{gathered}

The correct answer is:


(16)/(25)
