    20%

    Explanation:

    The frequency is the number of times a given thing appears in a specific period of time.

    In the given situation, you have a total of 80 cows, amongst these 16 have black and white coat and 64 have solid black coats.

    To find the frequency of black and white coats you need to simply find it probability.

    This would be = No. of cows with black and white coats / total number of cows

    using this formula we get = > 16/80 = 2/10

    Therefore frequency in terms of percentage would be 2/10 X 100 = 20%.
