The Aon Center is taller. You just need to look at the place values, like 5 and 10. Which is bigger? the ten of course.
Answer:
![\frac{1}{270}=0.00370](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B270%7D%3D0.00370)
Step-by-step explanation:
As the numbers are only between 1 and 30
Total number of possible combinations = 30×30×30 = 27000
If there are 100 attempts then
![\text{P (someone guesses correct)}=\frac{\text{Number of attempts}}{\text{Total number of possible combinations}}\\\Rightarrow \text{P (someone guesses correct)}=\frac{100}{27000}\\\Rightarrow \text{P (someone guesses correct)}=\frac{1}{270}=0.00370](https://tex.z-dn.net/?f=%5Ctext%7BP%20%28someone%20guesses%20correct%29%7D%3D%5Cfrac%7B%5Ctext%7BNumber%20of%20attempts%7D%7D%7B%5Ctext%7BTotal%20number%20of%20possible%20combinations%7D%7D%5C%5C%5CRightarrow%20%5Ctext%7BP%20%28someone%20guesses%20correct%29%7D%3D%5Cfrac%7B100%7D%7B27000%7D%5C%5C%5CRightarrow%20%5Ctext%7BP%20%28someone%20guesses%20correct%29%7D%3D%5Cfrac%7B1%7D%7B270%7D%3D0.00370)
∴ Probability someone can guess the correct combination given 100 attempts is ![\mathbf{\frac{1}{270}=0.00370}](https://tex.z-dn.net/?f=%5Cmathbf%7B%5Cfrac%7B1%7D%7B270%7D%3D0.00370%7D)
Here's a photo of the solution. Hope it helps and please give brainlist!
x= morning
y = afternoon
x + y = 10
x=10-y
5x + 6y =57
5(10-y) +6y =57
50-5y +6y =57
y=7
x=10-7 =3
check 3*5 = 15, 7*6 = 42, 42 + 15 = 57
