In the Blackpink Born Pink Concert, if 12 lucky Blinks (Blackpink fans) were chosen to take a picture with Jennie, Lisa, Rose, and Jisoo numbered from 0 to 11. With only 12 slots for the picture taking, the lucky Blinks are selected using the last two (2) digits of their ticket code. Using hashing function, which slot will be assigned to the lucky Blinks that has these last two digits on their concert ticket: 04, 15, 27, 39, 43, 55, 62, 33? If there is a collision, resolve it using quadratic probing. a. 04 will be assigned to slot number b. 15 will be assigned to slot number c. 27 will be assigned to slot number d. 39 will be assigned to slot number e. 43 will be assigned to slot number f. 55 will be assigned to slot number g. 62 will be assigned to slot number h. 33 will be assigned to slot number

Decode the number using the given private key. Decode the number M - 15 using the private key d = 53 and n = 77. Assume you are decoding the number using the RSA cryptosystem Note: You can use the Modular Exponentiation calculator to help with the calculation.
Q1: A craftsman has three identical boxes, each with two identical drawers. In the first box, one drawer contains 6 flange nuts, and the other drawer contains 5 hex bolts. In the second box, one drawer contains 4 flange nuts, and the other drawer contains 6 hex bolts. In the third box, one drawer contains 7 flange nuts, and the other drawer contains 4 hex bolts. 1. If he selects a box at random, opens a drawer at random, and finds a flange nut. What is the probability that box I was selected? 2. If he selects a box at random, opens a drawer at random, and finds a hex bolt. What is the probability that box III was selected?

(4) Elgamal public key cryptosystem (encryption): Start with the prime p = 17 and the primitive root g = 3. Alice sends Bob the public key A = 5. Bob wants to send the message m = 13 to Alice. Bob chooses the random element k = 2. Using the Elgamal public key cryptosystem, compute the pair of numbers (C₁, C₂) that Bob sends to Alice. Note: Do not work out how Alice computes the plaintext message m from the ciphertext (C₁, C₂).
