Question
a. Use the special addition rule to expressP(A orB) in terms ofP(A) andP(B). Complete the equation below. P(A or B)equals = b. Show that the
a. Use the special addition rule to expressP(A orB) in terms ofP(A) andP(B).
Complete the equation below.
P(A or B)equals
=
b. Show that the general addition rule gives the same answer as that in part(a).
Select the correct answer below.
A.
Since A and B are mutually exclusiveevents, then the probability that A or B occur is 1. Thatis, P(A)plus
+P(B)equals
=1. Under theseconditions, the general addition rule gives the same answer as that in part(a).
B.
Since A and B are mutually exclusiveevents, then the probability that both A and B occur is 0. Thatis, P(A)P(B)equals
=0. Under theseconditions, the general addition rule gives the same answer as that in part(a).
C.
Since A and B are mutually exclusiveevents, then the probability that both A and B occur is 0. Thatis, P(A& B)equals
=0. Under theseconditions, the general addition rule gives the same answer as that in part(a).
D.
Since A and B are mutually exclusiveevents, then the probability that A or B occur is 1. Thatis, P(A& B)equals
=1. Under theseconditions, the general addition rule gives the same answer as that in part(a).
