Ans1) Since ramesh wants only good shirts so,
Probability of ramesh buying the selected shirt is :
88(good shirts)/100(total shirts)
=0.88
Ans2) While since kewal won't buy only thr shirts having any major defect so his probability of buying the selected shirt is :
88(good shirts)+8(shirts with minor defects)/100(total shirts)
=>96/100
=0.96
