A) \[1/2\]
B) \[1/4\]
C) \[1/3\]
D) \[1/6\]
Correct Answer: A
Solution :
We know, \[P(A'\cap B')=1-P(A\cup B)\] \[\Rightarrow \] \[P(A\cup B)=1-\frac{1}{3}=\frac{2}{3}\] \[\therefore \] \[P(A\cup B)=P(A)+P(B)-P(A\cap B)\] \[\Rightarrow \] \[\frac{2}{3}=x+x-\frac{1}{3}\] \[\Rightarrow \] \[x=\frac{1}{2}\]You need to login to perform this action.
