Step1: Recall probability - complement formula
The formula for the probability of the complement of an event $A$, denoted as $P(\overline{A})$, is $P(\overline{A})=1 - P(A)$.
Step2: Substitute given value
Given $P(A) = 0.75$, we substitute it into the formula: $P(\overline{A})=1 - 0.75$.
Step3: Calculate result
$P(\overline{A})=0.25$.
