Explanation / Answer

Ans:

P(responded or between 22-39)=P(responded)+P(22-39)-P(responded and between 22-39)

Now,

P(responded) =1043/1225

P(22-39)=(274+277)/1225=551/1225

P(responded and between 22-39)=(254+244)/1225=498/1225

P(responded or between 22-39)=(1043+551-498)/1225

=1096/1225=0.895
