# Finding the equation of a line for a segment
The task is: given the coordinates of the ends of a segment, construct a line passing through it.
We assume that the segment is non-degenerate, i.e. has a length greater than zero (otherwise, of course, infinitely many different lines pass through it).

# Conditional expectation and variance
Let X, Y be independent exponential random variables with means 1 and 2 respectively.
Let
Z = 1, if X < Y
Z = 0, otherwise
Find E(X|Z) and V(X|Z).
We should first find E(X|Z=z)
E(X|Z=z) = integral (from 0 to inf) of xf(x|z).
