A) \[\frac{39}{64}\]
B) \[\frac{21}{64}\]
C) \[\frac{9}{64}\]
D) \[\frac{15}{64}\]
Correct Answer: B
Solution :
\[\left( \frac{3}{4} \right)\left( \frac{1}{2} \right)\left( \frac{3}{8} \right)+\left( \frac{1}{4} \right)\left( \frac{1}{2} \right)\left( \frac{3}{8} \right)+\left( \frac{3}{4} \right)\left( \frac{1}{2} \right)\left( \frac{3}{4} \right)\] \[=\frac{12+9}{64}\] \[=\frac{27}{64}\]You need to login to perform this action.
