question help: message instructor

Explanation:

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

$P(\overline{A})=0.25$.

Answer:

$0.25$
