WebFind the number of elements in the intersection of sets. Solution: Given: Set A = {a,b,c,d,e,f,g,h,i} and Set B = {a,e,i,o,u}. Thus, A ∩ B = {a, e, i} (common elements of the sets A and B). Then, n (A ∩ B) = 3 Answer: n (A ∩ B) = 3. Example 2: Let P = {1, 2, 3, 5, 7, 11}, Q = {first five even natural numbers}. WebAnswer (1 of 2): There are three elements.

WebThe number of reflexive relations on an n-element set is 2n (n-1) How does this formula work? A relation R is reflexive if the matrix diagonal elements are 1. If we take a closer look the matrix, we can notice that the size of matrix is n 2. The n diagonal entries are fixed. For remaining n 2 – n entries, we have choice to either fill 0 or 1.
