A) \[0.28\]
B) \[0.20\]
C) \[0.35\]
D) \[0.15\]
Correct Answer: A
Solution :
Given, \[P\left( \frac{H}{F} \right)=0.7,\,\,P(H)=0.5\] and \[P\,\,(W)=0.4\] \[\therefore \] \[P\left( \frac{H}{W} \right)=\frac{P(H\cap W)}{P(W)}\] \[\therefore \] \[0.7=\frac{P(H\cap W)}{0.4}\] \[\Rightarrow \] \[P(H\cap W)=0.28\]You need to login to perform this action.
