10² - 2 (8) + 11 . Use PEMDAS, which is the order of operation to follow:
P = parenthesis → 10² - 2x8 +11
E = exponent → 100 - 2x8 +11
M = Multiplication → 100 -16 +11
D = Division → NO DIVISION
A = Addition → 111 -16
S = Subtraction → 95 (answer 3)
Apply the same logic for the 2nd exercice and you will find 26 (I don't see the 26 in your answer but I am sure it's 26)
Answer: ![\bold{\dfrac{7}{8}=87.5\%}](https://tex.z-dn.net/?f=%5Cbold%7B%5Cdfrac%7B7%7D%7B8%7D%3D87.5%5C%25%7D)
<u>Step-by-step explanation:</u>
"At least one girl" means P(1 girl) + P(2 girls) + P(3 girls) or 1 - P(all boys)
I will use the latter: 1 - P(all boys)
P(all boys) = ![\dfrac{1}{2}\times \dfrac{1}{2}\times \dfrac{1}{2}=\dfrac{1}{8}](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B2%7D%5Ctimes%20%5Cdfrac%7B1%7D%7B2%7D%5Ctimes%20%5Cdfrac%7B1%7D%7B2%7D%3D%5Cdfrac%7B1%7D%7B8%7D)
![1 - P(all\ boys) \quad = \quad 1-\dfrac{1}{8}\quad =\large\boxed{\dfrac{7}{8}}](https://tex.z-dn.net/?f=1%20-%20P%28all%5C%20boys%29%20%5Cquad%20%3D%20%5Cquad%201-%5Cdfrac%7B1%7D%7B8%7D%5Cquad%20%3D%5Clarge%5Cboxed%7B%5Cdfrac%7B7%7D%7B8%7D%7D)
