To determine the combined weight of all the candies that weigh \( \frac{1}{2} \) ounces, let's first analyze the provided list of weights. However, from the list you shared, it seems there is no entry for \( \frac{1}{2} \) ounces. The weights given are as follows:
- 1, 1, 2, 1, 1, 4, 2, 1, 1, 2, 1, 1, 2, 1, 3, 4, 1, 1, 4, 1, 1, 2, 2, 1, 1, 2
Since there are no entries for \( \frac{1}{2} \) ounces, the total weight of candies that weigh \( \frac{1}{2} \) ounces is \( 0 \) ounces.
If you meant a different weight, please clarify, and I'll be happy to help!
