THERE ARE FOUR  PEOPLE  IN MY FAMILY : MY FATHER,MY MOTHER,MY SISTER AND ME
Xin lỗi mọi người đã làm phiền, nhưng mình thật sự cần sự giúp đỡ. Ai có thể dành chút thời gian để trả lời câu hỏi mình đang mắc phải không?

Considering the gender of the family members, we can say that there are 2 males (father and me) and 2 females (mother and sister) in the family.

If we represent each person in the family with a variable, let's say x for father, y for mother, z for sister, and w for me, then the sum of all variables should equal 4 (x + y + z + w = 4).

There are a total of 4 people in the family, so there are 2 adults (father and mother) and 2 children (sister and me).
