(a) A' = {1,3,5,7,9,10}

(b) B' = {1,2,4,6,8,9,10}

(c) C' = {2,3,4,6,10}

  • ( ' ) sign means complement.

》 To answer the given set(s) you need to write down the universal sets.

Example:

U = {r,a,i,n,b,o,w}

》 Then denote or remove the element that you'll find on the given set.

Example:

U = {r,a,i,n,b,o,w}

Given: {b,o,w}

Answer: {r,a,i,n}
