Set. Builder. Form

Example

6. (i) If $U=\left\{x:0\le x\le 10,x\in W\right\}$ and $A=\left\{x:xisamultipleof3\right\}$, find A'

(ii) If U is the set of natural numbers and A' is the set of all composite number, then what is A ?

Q. (i) If U = {0: $\le $x $\le $10, x $\in $ W} and A = {x:x is a multiple of 3}, find A'.

(ii) If U is the set of natural numbers and A' is the set of all composite numbers, then what is A?

If U = {a,b,c,d,e,f,g,h}, A = {a,b,c,d} and B = {b,d,f,g}.
