Question

Given A={1, 2, 3, 4, 5), S={(x, y) : xe A, YE A}. If x + y < 5,
then ordered pairs satisfying the condition are​

Answer 1

Answer:

{(1,1),(1,2),(1,3),(2,1),(2,2),(3,1)}

Step-by-step explanation:

it is given that A={1,2,3,4,5}

and X and Y belongs to A and the given condition is X+Y <5.(X+Y is smaller than 5)

so, we will put the required no.s which satisfy the given condition one by one to make ordered pairs

so, the ordered pairs are { (1,1),(1,2),(1,3),(2,1),(2,2),(3,1) }.

Answer 2

The set of ordered pairs satisfying x+y < 5 is {(1,1), (1,2), (1,3), (2, 1), (2,2), (3,1)}
