The probability of a transformer that has been refurbished at a factory being defective is 0.15. An engineer wishes to buy 6 non-defective transformers from the factory. He will inspect transformers one by one until he gets 6 non-defective transformers. Suppose it takes just 20 minutes to inspect a non-defective transformer while the inspection of a defective transformer takes 1 hour. What is the mean of the total time (in minutes) that the engineer will spend on inspections? ( don't hand writing solution)
