Describe the problem if a boiler containing eight welds is manufactured in a small shop. When the boiler is completed quality inspector checks each weld. If more than, one weld is defective on a single boiler the person who made the boiler report to the foreman. 1. If √?% of all welds made by Mr. X are defective, evaluate the probability that all boiler made by him will have more than one defective weld. 2. Over a long period of time if √?% of all welds made by Mr. X are defective evaluate the probability that all boiler made by him will have less than 4 defective welds.
