6. There is a party of 1000 people in that party. Think that each person knows 100 other people at the party and it is random and Relation is mutual, if C knows D then D also knows C.

(a) What is the probability that 2 random chosen people know one and other(each other)?

(b) What is the probability that 2 random chosen people don't know one and other(each other) and do not have mutual relations?

(c) What is the probability that 2 randomly chosen people don't know one and other(each other) and have mutual relations?

1/ Imagine a party with n people. When a person comes to the party they go and shake hands with a few other people (but not necessarily everyone - in fact there can be unfriendly people who do not shake hands with anyone!). None of the attendees narcissistic enough to shake hands with themselves. Prove that there are two people who shake the same number of hands. For example, suppose 3 people attend the party and everyone shakes hand with...

10 couples go to a party (So 20 people in total). Each of the 20 people are randomly seated at a large round table with 20 chairs. Let Xi = 1, for i = 1, 2, . . . , 20, if the i th person is sitting next to the other person in their couple, and 0 otherwise. Let Y be the total number of people who are seated next to their partner. (Note that the Xi ’s all...

Suppose that the fraction of infected people in a city is p = 0.01. 100 people from the city board a small cruise. You can assume that the people are unrelated to each other and randomly chosen so that each person is infected independently with probability p. You can also ignore the possibility that they infect each other while boarding. Suppose that the virus test gives negative when the person has the virus with probability 0.2, and gives negative when...

For n > 2, suppose that there are n people at a party and each of these people shake hands (exactly one time) with all of the other there (and no one shakes hands with himself or herself). Find the total number of hand shakes by solving a non-homogeneous recurrence relation.

4. Consider a social network with 100 users in which each person knows on average 10 other people. Let G be the corresponding (undirected) graph where each user corresponds to a node such that if two users know each other then there is an edge between them. What is the total number of edges in G? Explain your answer. Hint: Use the formula that relates node degrees and number of edges.

The probability that a randomly chosen person is Rh-positive is 85%. What is the probability that a randomly chosen person is Rh-negative? What is the probability the next 5 people tested are Ph-positive? What is the probability that out of the 5 people who have tested at least one is Rh-negative? If two people get tested, what is the probability that one is Rh-positive and the other is Rh-Negative?
