anonymous · Answer

a should be a correct answer. YOu know profitability of being defective is 1.9%.
So you just take 2900 *(1.9/100)=55.1-->55 is correct one
If the question asks how many # of light bulbs not being defective
Then, we have 100%-1.9%=98.1% of not being defective
-->2900 *(98.1/100)=2844.9
