Answer:

Step-by-step explanation:
step 1
Find the lateral area
we know that
The lateral surface of a square pyramid is equal to the area of its four lateral triangular faces
so
![LA=4[\frac{1}{2}bh]](https://tex.z-dn.net/?f=LA%3D4%5B%5Cfrac%7B1%7D%7B2%7Dbh%5D)
where

----> slant height
substitute the values
![LA=4[\frac{1}{2}(25)(18)]=900\ m^{2}](https://tex.z-dn.net/?f=LA%3D4%5B%5Cfrac%7B1%7D%7B2%7D%2825%29%2818%29%5D%3D900%5C%20m%5E%7B2%7D)
step 2
Find the cost

6 purple, 4 blue, 10 green
"What is the probability that the marble picked will not be green?"
Well, simply all the purple and blue together :)
6 + 4 = 10
So, 10 marbles are not going to be green.
So, 10 green, 10 non-green.
So, our probability is 10 : 10
Which, simplified, is 1 : 1
