Question 1020223: A manufacturer makes two models of an item:modelI,which accounts for 80% of unit sales,and modelI I,which accounts for 20% of unit sales.Because of defects,the manufacturer has to replace (or exchange) 10% of its modelI and 18% of its modelI I.If a model is selected at random,find the probability that it will be defective. Answer by robertb(5830) (Show Source):
You can put this solution on YOUR website! P(defective) = P(defective AND model I)+ P(defective AND model II)
= P(defective|model I)*P(model I) + P(defective|model II)*P(model II)
= 0.10*0.80 + 0.18*0.20
=
