(a)
Given:
P(A) = 0.76 (1)
P(B) = 0.2 (2)
A and B are mutually exclusive
To find :
By Theorem:
(3)
Since A and B are mutually exclusive:
(4)
Substituting (4) in (3), we get:
(5)
Substituting (1), we get from (5):
(6)
So,
Answer is:
0.76
(b)
To find:
: (7)
From (4):
(8)
Substituting (8) in (7), we get:
(9)
Substituting (9) in (6), we get:
So,
Answer is:
0.76
