The complement of an event is the probability of all outcomes that are NOT in that event. For example, if \(A\) is the probability of hypertension, where \(P(A)=0.34\), then the complement rule is: \[P(A^c)=1-P(A)\]. In our example, \(P(A^c)=1-0.34=0.66\).This may seen very simple and obvious, but the complement rule can often … do woodlice have a skeleton
