A fair die is rolled repeatedly. Let Xn denote the largest score after n rolls n = 1,2... For example if outcomes of the first five rolls are 4, 4, 2, 6, and 3 then x3 = 4 and x5 = 6. Is Xn n = 1, 2 a Markov chain? If so, determine the transition probability matrix.

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure
