Textbook Question
Chapter 7, Problem 2E
(Adapted from Barwise and Etchemendy (1993).) Given the following, can you prove that the unicorn is mythical? How about magical? Horned?
If the unicorn is mythical, then it is immortal, but if it is not mythical, then it is a mortal mammal. If the unicorn is either immortal or a mammal, then it is horned. The unicorn is magical if it is horned.

Solve the following puzzle by translating statements into logical expressions and reasoning fromthese expressions.Four friends have been identified as suspects for an unauthorized access into a computer system.They have made statements to the investigating authorities.1-Alice said Carlos did it.2-John said I did not do it.3-Carlos said Diana did it.4-Diana said Carlos lied when he said that I did it.If the authorities also know that exactly one of the four suspects is telling the truth, who didit?
For (∃ x)(P(x,b))
Would an example of this being true if the domain was all the Avengers and x was green skin, then "b" being the Hulk would make this true.
Am example of this being false would be:
If the domain was all integers and x was positive, even integers and "b" was integers greater than zero.

You have n particular focuses (x1,y1),… ,(xn,yn) on the plane and a non-negative integer boundary k. Each point is a tiny steel ball and k is the draw in force of a ball when it's charged. The draw in power is something very similar for all balls.
In one activity, you can choose a ball I to charge it. When charged, all balls with Manhattan distance all things considered k from ball I move to the situation of ball I. Many balls may have a similar facilitate after an activity.
All the more officially, for all balls j with the end goal that |xi−xj|+|yi−yj|≤k, we dole out xj:=xi and yj:=yi.
An illustration of an activity. Subsequent to charging the ball in the middle, two different balls move to its position. On the right side, the red dab in the middle is the normal situation of those balls.
Your errand is to observe the base number of activities to move all balls to a similar…

- Formulate your own argument (make it creative!) and draw a suitable Euler diagram for it. Justify as well whether it is valid or not. You may emulate the four given arguments below. Example: All Filipinos enjoy singing. Juan is a Filipino. Therefore, Juan enjoys singing. Some physicists are poets. Einstein is a physicist. Therefore, Einstein is a poet. All lions are animals. Some lions have manes.Therefore, some animals have manes. All booms (B) are zooms (Z). All feeps (F) are meeps (M). No boom is a feep. Therefore, no zoom is a meep.arrow_forwardConsider "knights and knaves" puzzles. These logic puzzles take place on an island with two types of people: the knights, who always tell the truth, and the knaves, who always lie. Now, write the solutions for the following questions: (a) On the island of knights and knaves, you are approached by one person. The person says to you, " I am a Knave or today is the rainy day on the island. (Which type is the speaker, and is there is a rainy day on the island?)." What are they actually? Someone asks person A on the island, “Are you a knight?” He replies, “If I am a knight then my sister is also knight.” Using logic & truth table prove that A is telling truth.arrow_forwardFour mathematicians have a conversation, as follows: ALICE: I am insane. BOB: I am pure. CHARLES: I am applied. DOROTHY: I am sane. ALICE: Charles is pure. BOB: Dorothy is insane. CHARLES: Bob is applied. DOROTHY: Charles is sane. You are also given the following information: Pure mathematicians tell the truth about their beliefs. Applied mathematicians lie about their beliefs. Sane mathematicians' beliefs are correct. Insane mathematicians' beliefs are incorrect. With the preceding clues, classify the four mathematicians as applied or pure, and insane or sane. Briefly explain your logic.arrow_forward

- Tom and Jerry recently saw the movie inception. Inspired by that movie they decided to play a complicated game. Analogous to the movie inception, Jerry is the dreamer and Tom is the thief who enters Jerry's dream in order to extract the secret code. Tom wins the game if he is able to extract the secret code, else Jerry wins the game. Note that here Tom has to extract the idea from Jerry. Tom after performing a lot of mathematical analysis finally ended up to one last step for which he requires a little computation. He has got an array of positive integers. If atleast one of them is prime, he will be able to crack the secret code and win the game, else Jerry wins the game. Input The first line contains a single integer t (1≤t≤106) the number of test cases. Description of each test case is as follows. The first line of each test case contains a single integer n (1≤n≤2⋅106) the number of elements in the array. The second line of each test case contains n positive integers…arrow_forward4.
