Choose the correct answer below. O A. A permutation of r objects from a collection of m objects is any unordered arrangement of r of the m objects. OB. A permutation of r objects from a collection of m objects is any ordered arrangement of r of the m objects. OC. A permutation is the product of the first k positive integers (counting numbers) and is denoted k!. OD. A permutation, NPn, is the number of possible samples of size n from a population of size N. b. Choose the correct answer below. O A. A combination, NC, is the number of possible samples of size n from a population of size N. O B. A combination of a counting number is obtained by successively multiplying it by the next smaller counting number until reaching 1. OC. A combination of r objects from a collection of m objects is any unordered arrangement of r of the m objects. OD.
