Answer :
If an event has a probability of "A", the complement of that event will have a probability of "1 - A".
Now, given the probability of an event is 3/25, we can easily find the probability of the complement of that event to be:
[tex]\begin{gathered} 1-\frac{3}{25} \\ =\frac{25}{25}-\frac{3}{25} \\ =\frac{22}{25} \end{gathered}[/tex]The answer is:
[tex]\frac{22}{25}[/tex]
