Question

A = {1,2,3,4,5} and B={(x,y) : x and y belong to A } , find the number of ordered pairs which satisfy the condition x+y greater than 8​

Answer 1

Step-by-step explanation:

☜☆☞A=(1,2,3,4,5) B(x,y)

☜☆☞we have to tell the number which should satisfy the condition x+y greater than 8

☜☆☞ now we have to take cases in this question

☜☆☞case1: if we take x=1 then we have to take a number greater than 7 to get answer greater than 8. but it is not possible

☜☆☞so from above numbers we can conclude that B=(4,5) satisfied the condition x+y greater than 8
