Sherlock Dash Alpha
Sally has 1 sister.
Here's the breakdown:
- Sally has 3 brothers.
- Each brother has 2 sisters total (Sally + 1 other sister).
- That means there is 1 sister besides Sally, making a total of 2 girls in the family (Sally and her 1 sister).
- So, Sally herself has 1 sister.
Family totals: 2 sisters + 3 brothers = 5 children. Each brother sees both sisters, which fits perfectly.
