If n a 2 n b 4 and n a ∪ b 6 find n a ∩ b
WebExplanation of the correct option. Given: n ( A) = 4 and n ( B) = 6. Since n B > n ( A) and the function is one-one function. Thus, the number of one-one functions mapping from A to B is P n ( A) n ( B) = P 4 6 = 6! ( 6 - 4)! ∵ P r n = n! n - r! = 6 × 5 × 4 × 3 × 2! 2! = 360 Hence, option (D) i.e. 360 is the correct option. Suggest Corrections 0 WebA set function h: 2[n] → Ris submodular if h(∅) = 0 and h(A) +h(B) ≥ h(A ∩B) +h(A ∪ B) for any A,B ⊆ [n]. Submodular functions are bijectively corresponding to the generalized permutohedra as their support functions. Therefore a CI-structure G ⊆ An is a semimatroid iff there is a submodular function h: 2[n] → Rsuch that
