The sum of the probabilities of complementary events given the same condition is always 1, as either the event or its complement must occur.

For Any Events A and B,P(A∣B)+P(AC∣B)=1, A \text { and } B , P ( A \mid B ) + P \left( A ^ { C } \mid B \right) = 1 \text {, }A and B,P(A∣B)+P(AC∣B)=1,

For Any Events $A \text { and } B , P ( A \mid B ) + P \left( A ^ { C } \mid B \right) = 1 \text {, }$
