A) 0.3
B) 0.35
C) 0.15
D) 0.5
Correct Answer: A
Solution :
P = 0.25, P = 0.50 and P (B/A) = 0.6 \[\Rightarrow \] \[\frac{P(B\cap A)}{P(A)}=0.6\] \[\Rightarrow \] \[P(B\cap A)=0.6\times 0.25\] \[\Rightarrow \] \[P(B\cap A)=0.150=P(A\cap B)\] \[P(A/B)=\frac{P(A\cap B)}{P(B)}\] \[=\frac{0.150}{0.50}\] \[=0.3\]You need to login to perform this action.
