If you knew {q1,..., qN} in advance, how should you choose {pi} to maximize the probability you successfullyprevent an attack? There are N sites that need protection (number them 1 to N). Someone is going to pick one of them to attack, andyou must pick one to protect. Suppose that the attacker is going to attack site i with probability q;. You plan onselecting a site to protect, with probability p; of selecting site i. The choice of {q;i} and {pi} represent the attacker'sand defender's strategy, respectively.

Given, that the attacker is going to attack site i with probability qi a site to protect, with…

Answered: There are N sites that need protection…

In a town, there are three bridges: Bridge A, Bridge B, and Bridge C. On any given day, the probability of each bridge being open for passage is as follows: P(A) = 0.4, P(B) = 0.3, and P(C) = 0.5. If a resident needs to cross all three bridges in succession, what is the probability of successfully crossing all three bridges without encountering any closures?
Dace is a political analyst for a presidential candidate (Aspirant A) with two strong competitors (Aspirants B and C). She analyzed that B and C have exactly the same chance of winning a seat while A has twice the chance of either B and C. With the given information, what is the chance of A in winning.
Factories A, B and C produce computers. Factory A produces 4 times as many computers as factory C, and factory B produces 6 times as many computers as factory C. The probability that a computer produced by factory A is defective is 0.038, the probability that a computer produced by factory B is defective is 0.035, and the probability that a computer produced by factory C is defective is 0.047. A computer is selected at random and it is found to be defective. What is the probability it came from factory B? Answer:

There are 3 light switchas in a row and each switch can either be On or Off. Use information to answer parts a and b below. Part A: when considering all possible light switch settings, give the probability of having at least one light switch On. Part B: when considering all possible light switch settings, and using odd notation, give the odd in favor of having exactly one light switch On
There are two bags A and B. Bag A contains n white balls and 2 black balls while bag B contains 2 white balls and n black balls. One of the two bags is selected at random and two balls are drawn from it without replacement. We know that if both the balls drawn are white balls, the probability of bag A being selected to draw the balls is . Find the value of n.
You are the teacher of two math classes of 20 and 25 students respectively. To get into a university program, the students need a 75% in the class. Suppose each student has a 0.7 probability of getting atleast a 75% in the class. Let X1 be the number of students in the class of 20 who receive atleast a 75%. Let X2 be the number of students in the class of 25 who receive atleast a 75%. a. Do X1 and X2 fit the binomial setting? Are there any issues? For the rest of the question, assume both X1 and X2 can be modeled by a binomial distri- bution. b. What is the probability that exactly 15 students in the class of 20 get into the pro- gram? Do not use Table C. c. What is the probability that atleast 22 students in the class of 25 get into the pro- gram? Do not use Table C. d.
