A) (a) 0.11
B) (b) 0.25
C) (c) 0.39
D) (d) 0.45
Correct Answer: C
Solution :
[c] \[\because P\left( A \right)=0.25\] \[P\left( B \right)=0.50\] \[P\left( A\cap B \right)=0.14\] \[P\left( A'\cap B' \right)=P\left( A\cup B \right)'\] \[=1-P\left( A\cup B \right)=1-\left[ P\left( A \right)+P\left( B \right)-P\left( A\cap B \right) \right]\]\[=1-\left( 0.75-0.14 \right)=1-0.61=039.\] Hence, option [c] is correct.You need to login to perform this action.
