A) \[\frac{1}{3}\]
B) \[\frac{2}{3}\]
C) \[\frac{6}{6}\]
D) None of these
Correct Answer: B
Solution :
(b): Let A be the event of reading English and B is the event of reading French. Then \[P(A)=\frac{45}{100}=\frac{9}{20},\,\,\,\,\,\,\,P(B)=\frac{30}{100}=\frac{3}{10}\] and \[P(A\cap B)=\frac{20}{100}=\frac{1}{5}\] \[P\left( \frac{A}{B} \right)=\frac{P(A\cap B)}{P(B)}=\frac{\frac{1}{5}}{\frac{3}{10}}=\frac{2}{3}\]You need to login to perform this action.
