Consider the shift cipher encryption So for all k = {a, b, c, , d, e, f, g, , h, 1, i, j, k, l, m, n, o, , p, r, s, , t, u, , v, y, z) Let say Pr[M = 'and'] =0.25, Pr[M= 'the'] =0.25, Pr[M= 'bye'] = 0.2, and Pr[M = 'sad'] = 0.3 Choose your question correctly: What is Pr[M = 'sad' | C = 'cil'] ? (Girls in the class will answer) What is Pr[M= 'bye' | C='hfk'] ? (Boys in the class will answer)
