5.2 addition rule and rule of complements Flashcards
1
Q
compound event
A
an event formed by combining two or more events, usually using the general addition rule: for any two events P(A or B)=P(A)+P(B)-P(A and B)
2
Q
addition rule for mutually exclusive events (ex: winning and losing in a game, doing a right and left turn)
A
if events a and b are mutually exclusive, then P(A and B)=0 or P(A or B)=P(A)+P(B)
3
Q
Complements
A
P(A^c)=1-P(A) if A is any event, the complement of A is the event that A does not occur. The complement of A is denoted A^c
