Given:
[tex]W=\lbrace t|t\in Z,t\text{ is odd, and \mid t\mid}\leq6\rbrace[/tex]
Required:
We need to find |W|.
Explanation:
We need to find the number of terms in the given set W.
We know that Z is the set of integers.
[tex]|t|\leq6\text{ means the absoluate values of the intergers less than or equal to 6,}[/tex][tex]|-6,-5,-4,-2,-1,0,1,2,3,4,5,6|\text{ }\leq6[/tex]
Select the odd numbers.
[tex]W=\lbrace-5,-3,-1,1,3,5\rbrace[/tex][tex]|W|=6[/tex]
