Question

Find set A' U C'.

U= {b, c, d, e, f, g, h, i, j}
A = {d, f, i}
B = {h, i, j}
C = {f, g, h, i, j}

Answer 1

`\sf{Solution:}`

`\sf{A'=U-A=\{b,c,d,e,f,g,h,i,j\}-\{d,f,i\}=\{b,c,e,g,h,j\}}`

`\sf{C'=U-C=\{b,c,d,e,f,g,h,i,j\}-\{f,g,h,i,j\}=\{b,c,d,e\}}`

`\sf{\therefore \ A' \cup C'=\{b,c,e,g,h,j\}\cup \{b,c,d,e\}=\{b,c,d,e,g,h,j\}}`
