A) 0.64
B) 0.65
C) 0.61
D) 0.63
Correct Answer: A
Solution :
[a] \[P\left( A\cap B \right)=0.32\] \[P\left( b \right)=0.5\] \[\therefore P\left( \frac{A}{B} \right)=\frac{P(A\cap B)}{P(B)}=\frac{0.32}{0.5}=\frac{32}{50}=\frac{16}{25}=\frac{64}{100}=0.64\]Hence, option [a] is correct.You need to login to perform this action.
