Expert Answer
R = {(x, y): x is the wife of y}
Now,
(x, x)
R
Since x cannot be the wife of herself.
R is not reflexive.
Now,
(x, x)
RSince x cannot be the wife of herself.
R is not reflexive.Now, let (x, y)
R x is the wife of y.Clearly y is not the wife of x.
(y, x) RIf x is the wife of y, then y is the husband of x.
R is not transitive.Let (x, y), (y, z) R
? x is the wife of y and y is the wife of z.
This case is not possible. Also, this does not imply that x is the wife of z.
(x, z) R
R is not transitive.
R? x is the wife of y and y is the wife of z.
This case is not possible. Also, this does not imply that x is the wife of z.
(x, z) RR is not transitive.Hence, R is neither reflexive, nor symmetric, nor transitive.
