(a)
The number of even integers in the set
Given information:
The set of integers
Concept used:
Those integers which are divided by
Calculation:
One integer is either even or odd. Generally even and odd integers are occurred alternately. 1 is odd, 2 is even, 3 is odd, 4 is even and so on.
Proceeding in that way we can say half of the total number of integers given in the set is even.
Total number of integers in the set
(b)
The number of odd integers in the set
(c)
The number of ways can two integers be selected from the set
(d)
The number of ways can two integers be selected from the set
