p = 0.513
Step-by-step explanation:
There are 212 families with exactly 3 children. So in all, there are 212*3 = 636 children.
Of those,
The number of girls is:
81 + 76*2 + 31*3 = 326
That is, 326 girls out of 636 children.
Then
See each answer below.
1) If we subtract 7 from both sides and try to take the square root, we are taking the square root of -7. Therefore, there are no solutions.
2) Dividing by 3 and taking the square root gives an answer of 0.
3) Add 4, multiply by 4 and finally take the square root of each side.You will get positive or negative four.
4) Divide by 4 and then take the square root. You have positive or negative 5/2.
