Exercise 14 Page 723

Since we have the symbol ⋂, we are looking for the intersection of the given sets. Y&={2,6,9,10,16} Z&={z | z is an even whole number less than 19}Let's rewrite the set Z as a set of all integers that are even and less than 19. Y&={2,6,9,10,16} Z&={0,2,4,6,8,10,12,14,16,18} The intersection of two sets is the set that contains elements that are common in both sets. An element is in the intersection of Y and Z if it belongs to Y and to Z at the same time. Y&={ 2, 6,9, 10, 16} Z&={0, 2,4, 6,8, 10,12,14, 16,18} Y ⋂ Z &={2,6,10,16}
