questions 13, 14 and 15 please they are multichoice thank you QUESTION 13Suppose that 20% of all copies of a particular textbook fail a certain binding strength test. Let X denote the number of books among 15 randomly selected copies that failthe test. Find the probability, to 3 decimal places, that at least 7 copies fail the test.a. 0.018O b.0.986O C. 0.982O d. 0.014QUESTION 14Suppose that two fair, 6-sided dice are tossed. What is the probability that the sum of the two scores equals 10 given that it is strictly greater than 7?O a. 1/7O b.3/36OC. 15/36O d. 1/5QUESTION 15For any two random variables X and Y, choose all the correct answers:Note that you will get a penalty mark for choosing an incorrect answer.There is no penalty for not choosing a correct answer, but also no marks are awarded for a correct answer that is not selected.· If X and Y are uncorrelated then X and Y are independent.a.O b.if X and Y are independent then X and Y are uncorrelated.OC. If X and Y are independent then P(X=x,Y=y) = P(X=x)P(Y=y) for every x and y.O d. if x and Y are independent then P(X=x|Y=y) = P(X=x) for every x and y.Ue. If X and Y are independent then for every x and y. PIX = x) = [ odds(X =x|Y =y)]/[1+odds(X = x | Y = y)]
