    The spinner has 5 equal sections, with one section red.

    It can have 5N equal sections, with N sections Red

    Step-by-step explanation:

    p (red) = 6/30 = 1/5

    1/5 = 2/10

    Out of 10 sections, 2 are Red

    In general,

    It can have 5N equal sections, with N sections Red

    6 out of 30 times would be written as

    6/30 which reduces to 1/5 which would mean the spinner is divided into 5 different colors.

    There could be more than one solution. The spinner could be divided into 10 spaces and red could be 2 of the spaces, or any other multiple of 5s
