We have that to find the possible values of x-y
We permutate every value of x minus every value of y
i.e
x(3,4)-y(2,3,4,5,6)
From the question we are told that
2< x < 5
1 < y<7.
Generally We know that
x is range of numbers from
3,4
y is range of numbers from
2,3,4,5,6
Therefore to find the possible values of x-y
We permutate every value of x minus every value of y
i.e
x(3,4)-y(2,3,4,5,6)
