Step-by-step explanation:
Represent the diagonals as:
Required
Determine the coordinate of the intersection
To do this, we simply calculate the midpoint of AC or BD.
For AC:
The midpoint is:
This gives:
For BD:
The midpoint is:
This gives:
Notice the midpoints are the same:
<em>Hence, the coordinates of the intersection is (2,1)</em>
Let 
be a probability that i-th light fails, where i=1,2,3. Then, 
is the probability that i-th light remain bright.
