If x is a geometric random variable, show analytically that p(x = n+k|x > n) = p(x = k) .give a verbal argument using the interpretation of a geometricrandom variable as to why the preceding equation is true. a geometric random variable is a discrete random variable with aprobability mass function defined as follows: p(n)=(1-p)n-1p, n=1, 0 < p < 1.
