... precede C and E. Since there are 3! ways to arrange A, B, and D, and 2! ways to arrange C and E,bythe product principal, there are 3!2! = 12 lists in which A, B, and D precede C and E.Foreach of ... S 2 ∪ S 3 and S 2 and S 3 are disjoint, and so, by the sum principle, Equation 1.7 must hold. We now give a proof for general n and k.
