Question

Tenslips of paper with the digits from 1 to 10 are mixed and thenplaced in a random order. Assume that all permutations areequally likely. Let X be the number of times the sequence needs tobe read from left to right to observe all of the numbers inorder. For example, the sequence 1, 2, 3, 4, 5, 6, 7, 8, 9,10 onlyneeds to be read once, while the sequence 2, 10, 9, 5, 8, 6,3, 4, 1, 7 needs to be read six times. (1 _ _ _2, 3, 4 _ _ _5, 6, 7_ _ _ 8 _ _ _ 9 _ _ _10. Find E(X). (Hint: Write X as a sum ofsimpler random variables.)
