Answer 1

1/32

Explanation:

You want the probability of spinning a green then yellow given the spinner shown.

Probability

The probability of green is its area as a fraction of the whole: 2/8 = 1/4.

The probability of yellow is its area as a fraction of the whole: 1/8.

The probability of any given sequence of colors is the product of the individual probabilities in that sequence:

P(green then yellow) = P(green)·P(yellow) = (1/4)(1/8)

P(green then yellow) = 1/32
