A) A and B are mutually exclusive events
B) A and B are dependent events
C) \[P\overline{\left( \frac{A}{b} \right)}=\frac{3}{4}\]
D) None of these
Correct Answer: C
Solution :
[c] 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, \[P\left( \frac{A}{B} \right)=\frac{1}{4}\Rightarrow P\overline{\left( \frac{A}{B} \right)}=1-\frac{1}{4}=\frac{3}{4}.\]You need to login to perform this action.
