Question 9 A diagnostic test for the presence of a disease has two possible outcomes: 1 for disease present and 0 for disease not present. Let X denote the disease state of a patient, and let Y denote the outcome of the :33\" diagnostic test. The joint probability mass function of X and Y is given by Marked out of P(X=0,Y=0) =0.800; P(X=1,Y=O)=0.050; P(X=0, Y=1)=0,025; P(X=1, Y=1 -0,125 1'00 Calculate the variance of the outcome of the diagnostic test for those with the disease. 222:: Select one: C) a. 0.15 O b. 0.71 O c: 0.13 C) d: 0.51 0 e. 0.204 Question 10 Not yet The joint probability mass function of random variables X and Y is given as follows: answered X Marked out of 1.00 1 2 Flag Y 1/8 2/8 question 2 2/8 1/8 3 1/8 0 4 0 1/8 Var(Y|X=2) is equal to Select one: O a. 2.9 O b. 1.5 O c. 2/3 O d. 1/3 O e. 2Question 11 Not yet Chapter 6 miniquiz answered Marked out of The joint probability mass function of two random variables X and Y is as follows: 1.00 Flag P(X=1,Y=1)=0.1; P(X=2,Y=2)= 0.35; P(X=2, Y =1)=0.05; P(X=1, Y=2)= 0.5. question The probability P(1
