Please include the argument in word, thanks

Let X ∼ Geom(p). For positive integers n, k define

P(X = n + k | X > n) = P(X = n + k) / P(X > n)

.

Show that P(X = n + k | X > n) = P(X = k) and then briefly argue, in words, why this is true

for geometric random variables.

Let n be a positive integer and p and r two real numbers in the interval (0,1). Two random variables X and Y are defined on a the same sample space. All we know about them is that X∼Geom(p) and Y∼Bin(n,r). (In particular, we do not know whether X and Y are independent.) For each expectation below, decide whether it can be calculated with this information, and if it can, give its value (in terms of p, n, and r)....
