A manufacturer of video game systems knows that 1 out of every 37 systems will be manufactured with some sort of error. If the manufacturer tests 123 of these systems at random before they leave the factory, what is the probability, in terms of percent chance, that none of these systems are defective (round your answer to the nearest hundredth)?

He ! a group of farmers planned to clean 80 acres of wheat per day to finish the work on schedule. right before the work started, they received a new piece of machinery that them clean 10 more acres per day than originally planned. as a result of increased productivity in the last day before the deadline they only had to clean 30 acres. how many acres of wheat did the group of farmers have to clean?
