A surprising result that appears in many elementy discussion on probability is called the birthday problem. The question simply stated is that if we pola certain number of people, what is the probability that at least two of those people were bom on the same day of the you? To solve this problem, use the formula for computing the probability of a complement of an event. It is clear that duplication of some birthdays) = 1 - Pino duplications. Assume...

We have seen that the probability that at least two people in a group of 23 people share the same birthday is approximately 0.5. In this question we are interested in the probability that at least three people in a group of 23 people share the same birthday. Draw 23 numbers independently from the integers {1, 2, . . . , 365} with each number equally likely to be drawn. Let E be the event that at least one of...

question One: Design an ER diagram for the following Dental Clinic database. Your diagram should have all the needed details. You may make any reasonable assumptions but you have to state them clearly. ------ The clinic has several dentists. Each dentist has a unique Number, name, nationality, multiple room-number, salary, birth-date and home-address (Box, City, Zip). Each client (patient) has a unique Code, name, home-phone, work-phone, address, and birth-date. Each client is assigned to one dentist. All future visits will...

7. Critical analysis Q11 Consider two occupations (A and B) in which people have the same skills and abilities. When employed, workers in the two occupations work the same number of hours per day. In occupation A, employment is stable throughout the year, while employment in occupation B is characterized by seasonal layoffs. The annual wage will be lower in occupation ___(A or B)

The soccer team's shirts have arrived in a big box, and people just start grabbing them, looking for the right size. The box contains 3 medium, 11 large, and 9 extra-large shirts. A player wants a medium for himself and one for his sister. Find the probability of each event described. Complete parts a through d below. a) The first two the player grabs are the wrong sizes. The probability that the first two shirts the player grabs are the...

. Consider your class of 29 students. Calculate the probability that at least two students have the same birthday. For this purpose, assume each day of the year is represented by a box, and we place the name of the student in the box corresponding to their birthday. (a) List total number of possible arrangements. (b) List total number of arrangements that do not have two names in the same box. Obtain the probability that no two students have the...

5.36. (a) In a group of 23 strangers, what is the probability that at least two of bout if there are 40 strangers? In a group them have the same birthday? How a of 200 strangers, what is the probability that one of them has the same birthday as your birthday? (Hint. See the discussion in Sect. 5.4.1.) (b) Suppose that there are N days in a year (where N could be any number) and that there are n people....

in python The birthday paradox says that the probability that two people in a room will have the same birthday is more than half, provided n, the number of people in the room, is more than 23. This property is not really a paradox, but many people find it surprising. Design a Python program that can test this paradox by a series of experiments on randomly generated birthdays, which test this paradox for n = 5, 6, 7, ..., 50....
