Plain-text version
A function is selected at random from all fhe functions of the set A = {1, 2, 3, ⋯, n} in to itself. The probability that the function selected is one-to-one is (A) 1/nⁿ (B) 2/((n-1)!) (C) 1/n! (D) ((n-1)!)/nⁿ⁻¹
Also written as: A function is selected at random from all fhe functions of the set A = {1, 2, 3,..., n} in to itself. The probability that the function selected is one-to-one is
