Step-by-step explanation:
Options:
a) Cone b) Cube
c) Cylinder d) Triangular prism
From the given options (a) to (d), option (a) is true.
This is so, because.
The volume (V) of a cone is:
This is as a result of dilating the cylinder by 1/3 whose volume is:
In other words:
<em>i.e. the cross-section of the cylinder (V2) being dilated by 1/3 (which is between 0 and 1) gives the cone (V1)</em>

Step-by-step explanation:
Answer:
1/20 or 0.05
Step-by-step explanation:
Assuming that all five posters are different, the number of ways to randomly place those posters is given by:
If we want the largest to be in the center and the next largest to be on its left, two poster will have a set position and only three could be randomized:
Therefore, the probability is:
The probability is 1/20 or 0.05.
