Chris wonders whether the planes that fly over his house follow any sort of pattern. For two months, he records whether each plane he sees follows a north-south route or an east-west route. He also records the day of the week that he sees each plane. Unfortunately, Chris dropped his data in the mud and can't read all of his numbers. The absolute and relative frequency tables below show the numbers that Chris is able to read. Can you help him figure out the rest?

Fill in the missing values from each table.
