    Answer:

    The probability of not spinning a 3 is \frac{8}{9}

    Step-by-step explanation:

    The probability of spinning a 3 is 1/9. What is the probability of not spinning a 3?

    Spinning a 3 and not spinning a 3 are complementary events, which means that the sum of their probabilities is decimal 1. So

    \frac{1}{9} + p = 1

    p = 1 - \frac{1}{9} = \frac{9}{9} - \frac{1}{9} = \frac{8}{9}

    The probability of not spinning a 3 is \frac{8}{9}
