Question
Question: If \(P ( A ) = \frac { 1 } { 4 } , P ( B ) = \frac { 5 } { 8 }\) and \(P ( A \cup B ) = \frac { 3 ...
If P(A)=41,P(B)=85 and P(A∪B)=43 then
P(A∩B)=
A
81
B
0
C
43
D
1
Answer
81
Explanation
Solution
P(A∩B)=82+85−86=81
If P(A)=41,P(B)=85 and P(A∪B)=43 then
P(A∩B)=
81
0
43
1
81
P(A∩B)=82+85−86=81
