Question: Robert Smith uses either regular plowing or minimal plowing to
Robert Smith uses either regular plowing or minimal plowing to prepare the cornfields on his Minnesota farm. Regular plowing was used for 40% of the field acreage. Analysis after the crop was harvested showed that 50% of the high-yield acres were from minimal plowing fields and 40% of the low yield fields were from fields with regular plowing. What is the probability of a high yield if regular plowing is used? What is the probability that a field with high yield had been prepared using regular plowing?
