A) A and B are mutually exclusive events
B) A and B are dependent events
C) \[P\left( \frac{A}{B} \right)=\frac{3}{4}\]
D) None of the above
Correct Answer: C
Solution :
We have,\[P(A)=P\left( \frac{A}{B} \right)=\frac{1}{4}\].This shows that\[A\]and\[B\]are independent events. So, \[P(B)=P\left( \frac{B}{A} \right)=\frac{1}{2}\] Now, \[P\left( \frac{A}{B} \right)=\frac{1}{4}\Rightarrow P\left( \frac{{\bar{A}}}{B} \right)=1-\frac{1}{4}=\frac{3}{4}\]You need to login to perform this action.
