Vedclass · Answer

(B) The probability of an event $A$ occurring is denoted by $P(A)$,and the probability of the event $A$ not occurring (the complement of $A$) is denoted by $P(\bar{A})$.Since an event either occurs or does not occur,these two events are complementary and exhaustive.Therefore,the sum of their probabilities is always equal to $1$,i.e.,$P(A) + P(\bar{A}) = 1$.

For any event $A$,which of the following is true?
