Solution :
Let the distance of the stick from one break be X
And let us assume that
.
Here, l = length of stick
Therefore, 
We know that,
, so by definition we get

The cumulative distribution function for R is

When it starts at zero, then r =0. It ends at one when the r has a maximum
value of one.
The probability density function is given by

Now integrating, we find E(R) and
gives :


Therefore, Var(R)= 
Answer:
( the third choice)
Step-by-step explanation:
Let
be the radius of cylinder A and let
be the radius of cylinder B. We assume the heights of both cylinders are the same
Base circumference of cylinder A = 
Base area of cylinder B = 
In order to have
(2) have the same value as
(3) we must multiply by a factor of
