Answer:
If you split the building into 2 parts, the first part (left) would be 8m × 10m × 4m = 320m3, and the second part (right) would be 8m × 4m × 6m = 192m3
320m3 + 192m3 = 513m3

Answer:
9/32
Step-by-step explanation:
given that an ant is moving on a numbered, horizontal line every second
Probability for moving left = 1/4
and prob for moving right =3/4
As this totals 1, there is no chance that ant will remain in the same posiiton after 1 second.
Either it has to move left or right.
Initial position is 0.
After 3 seconds it is in position 1.
The chances are I second move left, next second, move right and come to 0 and third second move to 1.
Or
I second move right, then left to 0, and third again to right to 1.
There are no other alternatives
Probability for this = ![\frac{1}{4} \frac{3}{4} \frac{3}{4} +\frac{3}{4} \frac{1}{4} \frac{3}{4} \\=\frac{9}{32}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B4%7D%20%5Cfrac%7B3%7D%7B4%7D%20%5Cfrac%7B3%7D%7B4%7D%20%2B%5Cfrac%7B3%7D%7B4%7D%20%5Cfrac%7B1%7D%7B4%7D%20%5Cfrac%7B3%7D%7B4%7D%20%5C%5C%3D%5Cfrac%7B9%7D%7B32%7D)
