Write down the complement of given sets:...

Write down the complement of given sets:
(i) A={x:x is an even integer}, Zis universal set
(ii) X={x:x-3=4, `x in N}`, N is universal set.

Text Solution

Verified by Experts

(i) A={x:x is an even integer `x in Z}`
A={,……, -4,-2,0,2,4,……}
A'= {……., -5,-3,-1,1,3,5………}
`therefore A'` ={x:x is an odd integer}
(ii) X={x:x-3, 4, `x in N}`
X={7}
X'={1,2,3,4,5,6,7,8,9,10……}
therefore X'={x:`x in N and x ne 7}`
