Explanation Given information: It is given that the set is { x 1 , x 2 , x 3 , x 4 , x 5 } . Concept used: Make a list of 3 elements out of 5 . Calculation: List out the all 3 -combinations for the set { x 1 , x 2 , x 3 , x 4 , x 5 } . Note that set of all 3 -combinations for the set { x 1 , x 2 , x 3 , x 4 , x 5 } is union of all 3 -combinations, so that the object x 1 is always included and the object x 1 is never included. First, consider all 3 -combinations so that the object x 1 is always included. Take the object x 1 . So, two more objects (elements) are required for a 3 -Combination. Those are { x 2 , x 3 } , { x 2 , x 4 } , { x 2 , x 5 } , { x 3 , x 4 } , { x 3 , x 5 } . { x 4 , x 5 } . Therefore, all 3 -combination so that the object x 1 , is always included are. { x 1 , x 2 , x 3 } , { x 1 , x 2 , x 4 } , { x 1 , x 2 , x 5 } , { x 1 , x 3 , x 4 } , { x 1 , x 3 , x 5 } { x 1 , x 4 , x 5 } . Next consider all 3 combinations so that the object x 1 is never included To determine (b) To list all unordered selections of two elements from the set { x 1 , x 2 , x 3 , x 4 , x 5 , x 6 } and also, find the value of ( 6 2 ) ! .

Set Theory

Every field in the present world involves a set. The theory of sets was developed by German mathematician Georg Cantor while working on the “problems of trigonometric series”.
