An article manufactured by a company consists of two parts X and Y. In the process of manufacturing of part X, 9 out 100 parts many be defective. Similarly , 5 out of 100 are likely to be defective in the manufacturer of Y. Calculate the probability that the assembled product will not be defective?
a)0.6485
b)0.6565
c)0.8645
d)none of these

• ans=c (0.8645)
  probablity of nondefective of x= 91/100=.91
  probablity of non defective of y= 95/100=.95
  so, probablity of nondefective product=.91*.95=0.8645

• 0.8645 if eithr x or y defctive , d assembled prt also defctive... so
  P(X or Y)=P(X)+P(Y)-P(XY)=9/100+5/100-((9/100)*(5/100))=0.1355
  Thus prob of non defective=1-0.1355=0.8645
