Now assume that Alice and Bob are twins, and Alice left Earth and Bob stayed behind fixing his spaceship. If Alice spent some time moving near the speed of light before returning to Earth, which statement is correct when Alice returns to Earth?

a. Alice will say that she is younger than Bob, and he will agree.

b. Bob will say that he is younger than Alice, and Alice will say that she is younger than Bob.

c. Alice will say that she is younger than Bob, and he will disagree.

Assume economy with two goods x and y and two people Alice and Bob. The MRSA of Alice is 15. The MRSB of the Bob is 10. (a) Is the current allocation of x and y is efficient? Why yes or why not? (b) Is there a trade that would be voluntary? Explain. Support your answer by graph. (c) Pareto Efficient Allocations, the Contract Curve and the Core. Define these three terms and explain the relationship between them. Use the...

Alice and Bob are supposed to meet in the cafeteria. Alice arrives at a random time between noon and 1pm, and wait for 15 minutes upon her arrival and then leaves. Bob also also arrives at a random time between noon and 1 pm, but waits up to 20 minutes and then leaves. (a) What is the probability that Bob arrives before 12:20? (b) What is the probability that Alice and Bob meet? (c) If Bob arrives later than Alice,...

:) Alice and Bob play the following game: in each round, Alice first rolls a single standard fair die. Bob then rolls a single standard fair die. If the difference between Bob’s roll and Alice's roll is at most one, Bob wins the round. Otherwise, Alice wins the round. (a) (5 points) What is the probability that Bob wins a single round? (b) (7 points) Alice and Bob play until one of them wins three rounds. The first player to...

Alice and Bob visit the gym on Saturday for their hourlong workouts. Alice always arrives between 2:00 and 3:00 and Bob between 2:30 and 3:30. Assuming their arrival times are drawn independently and uniformly from the specified intervals (i.e. any arrival time in the given window is equally likely), and assuming they each stay for precisely one hour, what is the probability that on any given Saturday there exists a moment in time when all two are present at the...

Both Alice and Bob toss a fair coin three times. The probability that Alice records a different numbers of heads than Bob is given by A/B, where A and B are relatively prime integers (greatest common divisor is 1). Find A + B.

How to generate a key pair for Alice and Bob Respectively Suppose Alice sends plaintext P= 113, how does she encrypt and whats the ciphertext C? After Bob receives C, how does he decrypts it to get the plaintext P? Suppose Alice sends plaintext P= 113, how does she sign it and what are sent to Bob. How does Bob verify the signature? Suppose Bob sends plaintext P=113, how does he sign it and what are sent Alice. How does...

Answer digital signatures question. assume Alice has the RSA key (eA, dA, nA) and Bob has the RSA key(eB, dB, nB), where eA, eB, nA, and nB are public, dA is known only to Alice, and dB is known only to Bob. (a) Describe how Alice could use her RSA key to sign a public message m, and explain why this approach satisfies the objective of non repudiation. (b) Describe how Alice could encrypt and send a secret message to...

RSA: Alice wishes to send Bob the message POET. Suppose Bob chooses P = 29, Q = 31, E = 47, and D = 143. Show the steps that Alice uses to encrypt the message POET (use the ascii values of the letters P, O, E, and T), and how Bob decrypts the message he receives from Alice. You will be generating very large numbers, and will find the following calculator helpful: https://www.calculator.net/big-number-calculator.html

Assume the following scenario: Bob plans to retire in 15 years from now and wants to have the following stream of CFs after retirement. Monthly payments of $6,000 for 10 years starting right after retirement (the first payment will be at the end of the first month of year 16). He then needs an extra 10000$ with the final payment (that is at the end of the final month of year 25). Starting from year 26 he wants the monthly...
