doubt....plz clear it

A permutation of n objects is a 1-1 function from A={1,2,.................n} to itself.If a₁,a₂,a₃.......a_k are n distinct elements of A such that a function f sends a₁ to a₂,a₂ to a₃ , .......... a_k-1- to a_k and a_k to a₁, then a₁,a₂,..a_k are said to form a cycle of length k. A permutaiton is chosen randomly from set of all permutations of set A={1,2,....n}

Q1 The probablity that chosen permuttion is a cycle such that 1-->2-->3-->...........(n-1)-->1 ??

Q2 Let a₁,a₂,...a_k ,b₁,b₂...b_k ε A be such that a_i 's are distinct and b_j 's are distinct.The

probablity that chosen permutation sends a_i -------> b_i for i=1,2,........k
