Verified step by step guidance1
Count the number of yellow regions on the spinner. There are 2 yellow regions out of a total of 6 regions.
Calculate the probability of landing on yellow for the first spin. This is the number of yellow regions divided by the total number of regions: \( \frac{2}{6} \).
Calculate the probability of not landing on yellow for the second spin. Since there are 4 non-yellow regions, the probability is \( \frac{4}{6} \).
Multiply the probability of landing on yellow on the first spin by the probability of not landing on yellow on the second spin: \( \frac{2}{6} \times \frac{4}{6} \).
Simplify the resulting fraction to find the final probability.
