Answer 1

To determine if Samedy is correct, we need to calculate the total number of brothers and sisters based on the information provided.

1. Students with 2 brothers or sisters:
   • 7 students × 2 = 14 brothers and sisters
2. Students with 1 brother or sister:
   • 4 students × 1 = 4 brothers and sisters
3. Students with no brothers or sisters:
   • 3 students × 0 = 0 brothers and sisters
4. Students with 3 brothers or sisters:
   • 6 students × 3 = 18 brothers and sisters
5. Remaining students with 4 brothers or sisters:
   • Total students = 24
   • Students accounted for = 7 + 4 + 3 + 6 = 20
   • Remaining students = 24 - 20 = 4 students
   • 4 students × 4 = 16 brothers and sisters

Now we add it all together:

• Total = 14 (from 2) + 4 (from 1) + 0 (from none) + 18 (from 3) + 16 (from 4)
• Total = 14 + 4 + 0 + 18 + 16 = 52 brothers and sisters.

So, Samedy is incorrect. In total, the class has 52 brothers and sisters.

To fill in the drop-down menus: Samedy is incorrect. In total, the class has 52 brothers and sisters.
