For this question, refer to the laws of propositional equivalence on BB. If we apply the law of absorption to rv (r^(p--> q)) we get the simpler proposition QUESTION 6 Suppose a proposition contains 5 distinct proposional letters (e.g. (pvq^p) -->q contains two distinct letters: p and q). How many distinct truth tables are possible? Hint: first determine the number of rows in the truth table 2^32 QUESTION 7 Which of the propositions below logically implies p ^ (p v q)? O pvq

Question 1 (35 marks) Two friends are exchanging messages through regular post mail. They don't want anyone to understand their messages in case anyone read them. The messages are in the form of an array of characters, where each character has a numeric value as illustrated in the below lookup table. A В D E F G H J K M 2 3 4 10 11 12 13 1 7 8 N PQR S TU V w X Y 14 15 16 | 17 18 19 20 21 22 23 24 25 26 They decided to change the characters in the array in a way that cannot be observed by any accidental reading. They do so as follows: 1- Given the original message, for example: GREETINGS 2- transform the original character to its numeric value 7 18 5 5 20 9 14 7 19 3- For each number, subtracting from its value the value of the first lower value character after it, and if there's no such character they will keep that character without any change. 2 13 5 5 11 2 7 7 19 7 18 5 5 20 9 14 7 19 2 13 5 5 11277 19 7 18 55 20 9 14 7 19 7-5 = 2 7 18 55 20 9 14 7 19 18-5 = 13 7 18 55 20 9 14 7 19…
