= = (c) Consider the random plaintext on two letters, P = {A, B}. We have the proba- bility distribution on A, B, given by p(A) = p, and p(B) = q. We take K = {0,1} with o the identity map on P and 7 the permutation that interchange A with B. We put on K the uniform distribution, with plo) = { = P(1). Finally, as a set C= P. 1. Show that if the probability on a sequence from Pn is the product of the probabilities for the n letters, then the probability that the cryptogram will be a specific sequence from Cn with m A's and n- m B’s, is rm 7.
