One jelly bean is picked, without looking, from the dish. Write a sentence that explains how likely it is for each event to happen.

  • Question 9 (request help)

    Persevere with Problems

    The probability of landing in a certain section on a spinner can be found by considering the size of the angle formed by that section. On spinner shown, the angle formed by the yellow section is one-fourth of the angle formed by the entire circle.
    So, P(yellow) = \( \large\frac{1}{4} \), 0.25, or 25%.

    a. Determine P(green) and P(orange) for the spinner. Write the probabilities as fractions, decimals, and percents.

    b. Determine P(not yellow).
