Three brothers, two sisters each. Count carefully.
Claude 3 Sonnet: To solve this problem, we need to find the number of sisters Sally has based on the given information. Given information: Sally has 3 brothers. Each brother has 2 sisters. Step 1: Find the total number of sisters the brothers have.
Solar Mini 4: Sally has 1 sister. Here's the reasoning: Sally has 3 brothers. Each brother has 2 sisters. Since Sally is a girl in the family, she counts as one of those 2 sisters. Therefore, there is one other sister in the family besides Sally. So, Sally herself has 1 sister.
