Exercise 1.15. Assume that the numbers 1,2, n are randomly given to players labeled 1,2,...,n. Initially,...
In a certain lottery, players pick 5 numbers (without replace) from the numbers 1-50 and an additional number (possibly repeated from the first set) from the numbers 1-30. A set of 6 numbers with these restrictions is then chosen uniformly at random. The player wins based on how many of their numbers matched the randomly chosen number. (a) What is the probability that the player chooses all 6 numbers correctly? (b) What is the probability that the player chooses exactly...
Exercise 14. Let bi,..., bn be distinct numbers, representing the quality of n people. Sup pose n people arrive to interview for a job, one at a time, in a random order. That is, every possible arrival order of these people is equally likely. We can think of an arrival ordering of the people as an ordered list of the form ai, . . . , an, where the list ai, . . . , an is a permutation of...
The game lets players know whether they have won, lost, or tied a particular game. Modify the game so the players are told the number of games they have won, lost or tied since the start of game play. Implement this change by adding three variables named $wins, $lost, and $ties to the program's Main Script Logic section, assigning each an initial value of 0. Next, modify the analyze_results method by adding programming logic that increments the values of $wins,...
program in python Randomness can be used to improve the performance of deterministic algorithms which need to make many choices. Rather than repeatedly making fixed, hard-coded choices, a pseudorandom number generator can be used to make dynamic, unbiased choices. If the benefits of "good" choices outweigh the costs of "bad" choices, a random selection of good and bad choices can improve the performance of an algorithm Let us explore this with the QUICKSELECT algorithm. Discovered by the influential computer science...
