1 answer:
The sum of the two fractional number, which consist in the variable <em>x</em> is in the polynomial function,
Fraction number is the number which is a part of a whole number. It is written with a numerator and denominator.
Fraction number are written as,
Here (a) is the numerator and (b) is the denominator.
To find the sum of two fraction numbers, cross multiply both the numbers or find the least common factor as denominator.
The first fraction number given in the problem is,

Answer with explanation:
→Number of Integers from 1 to 100
=100(50 Odd +50 Even)
→50 Even =2,4,6,8,10,12,14,16,...............................100
→50 Odd=1,3,,5,7,9,..................................99.
→Sum of Two even integers is even.
→Sum of two odd Integers is odd.
→Sum of an Odd and even Integer is Odd.
(a)
Number of ways of Selecting 2 integers from 50 Integers ,so that their sum is even,
=Selecting 2 Even integers from 50 Even Integers , and Selecting 2 Odd integers from 50 Odd integers ,as Order of arrangement is not Important, ,
=4900 ways
(b)
Number of ways of Selecting 2 integers from 100 Integers ,so that their sum is Odd,
=Selecting 1 even integer from 50 Integers, and 1 Odd integer from 50 Odd integers, as Order of arrangement is not Important,
=2500 ways
