I need to work through this step-by-step.
Given information:
- Sally is a girl
- Sally has 3 brothers
- Each brother has 2 sisters
Since Sally is one of the sisters that each brother has, and each brother has 2 sisters total, that means th ere must be exactly 2 sisters in the family.
The 2 sisters are:
