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)=
