Bob's RSA public key has modulus N = 12191 and exponent e = 37. Alice sends Bob the ciphertext c = 587. Unfortunately Bob has chosen too small a mosulus. Help Eve by factoring N and decrypting Alice's message. (Hint N has a factor smaller than 100)

There are three bags: a (contains 2 white and 4 red balls), b (8 white, 4 red) and c (1 white 3 red). you select one ball at random from each bag, observe that exactly two are white, but forget which ball came from which bag. what is the probability that you selected a white ball from bag a?
