An event (e.g., A ) and its complement are always mutuallyr exclusive. 15 P AI+P| A :1 16 When events are not mutually exclusive, die rule is: P ' A U B = PI AH P | B P [2 A n B} 17 Rule of addition when event are mutually exclusives: P EA U B 2 Pi A|+P :B 18 P SD A1 is not P AIB *P{Bl 19 The P(x) is always 0 g P(x} 3 1.
