A) \[\frac{11}{100}\]
B) \[\frac{39}{100}\]
C) \[\frac{35}{100}\]
D) \[\frac{22}{100}\]
Correct Answer: B
Solution :
[b] \[\therefore P\left( A\cup B \right)=P\left( A \right)+P\left( B \right)-P\left( A\cap B \right)\] \[=0.25+0.50-0.14=0.75-0.14=0.361\] \[\therefore P({A}'\cap B')=p(\cup uB)'\] [By Demorgen's Law] \[=1-P\left( A\cup B \right)=1-0.61=0.39=\frac{39}{100}\]You need to login to perform this action.
