nd markers without ink. Assume that the box contains 17 markers: 12 that contain ink and 5 tha ontain ink. A sample of 8 markers is selected and a random variable Y is defined as the number arkers selected which do not have ink. ow many different values are possible for the random variable Y? Part 2
Van Helsing is set to appear in the final exam of a Field Theory course, in which she is a student. If she has breakfast before the exam she is three times as likely to write all the answers on her own than copy from anyone else. If she does not eat breakfast, she is three times as likely to copy than to work independently. 6. If she works independently her score is (approximately) a Gaussian (70, 10) random variable. If she decides to copy, then she tosses a fair coin and copies all her answers from her friend Igor if heads appear, and from her classmate Drac, if tails appear. If she copies her answers from Igor then her score is (approximately) a Gaussian (73, 10) random variable. However if she chooses Drac, then he tells her all the wrong answers on purpose, in which case her Score is zero. A student fails if s/he scores 39.49 marks or below, although all the remaining grades are awared relative to the class average. The chances of Van Helsing having breakfast on the day of the…
Suppose that the genders of the three children of a certain family are soon to be revealed. Outcomes are thus triples of “girls” (g) and “boys” (b), which we write gbg, bbb, etc. For each outcome, let R be the random variable counting the number of girls in each outcome. For example, if the outcome is bbb, then R(bbb)=0. Suppose that the random variable X is defined in terms of R as follows: X=R^2-2R-1. The values of X are given in the table below.
In experiment of flipping two coins, each coin has two faces: Head and Tail. Each face is being equally likely to be drawn. If two random variables X and Y are defined as X(s) = Number of Heads appeared on both coins Y(s) = Number of Tails appeared on both coins The value of pxy (2,0) is 00.5 00 01 00.25
A system consists of four parts that work independently of each other. Working probabilities of these parts are given as 0.9 , 0.8 , 0.7 and 0.6, respectively. If the random variable X is defined as the total number of parts working in this system, calculate the probabilities P {X>0}, P {X=2} , the expected value and the variance.

You currently work for the DARPA, the Defense Advanced Research Projects Agency. You've received reports of some strange things occurring in the small town of Hawkins, Indiana. Let U be a random variable equal to 1 if the citizen has been to the Upside Down and 0 otherwise. Let S be a random variable equal to 1 if a citizen reports being in the presence of a group of misfit kids who claim to be "saving the town" and 0 otherwise The table below shows the joint probability density function for the galactic population Share of Population 0.15 0.32 0.50 0.03 U 0 0 1 1 S 1 0 1 0 Round to 2 decimal places where necessary, unless otherwise stated.
