Question
If P(A) = 0.59, P(B) = 0.30, P(A ∩ B) = 0.21 then P 
is :-
is :-Options
A.0.79
B.0.11
C.0.32
D.0.38
Solution
P(A) = 0.59, P(B) = 0.30
P(A ∩ B) = 0.21
P
= 1 - P(A υ B)
= 1 - {P(A) + P(B) - P(A ∩ B)}
= 1 - {0.59 + 0.30 - 0.21}
= 0.32
P(A ∩ B) = 0.21
P
= 1 - P(A υ B)= 1 - {P(A) + P(B) - P(A ∩ B)}
= 1 - {0.59 + 0.30 - 0.21}
= 0.32
