Let A a b c Let B xy Let C 0 1 List or describe the eleme

Let A = {a. b. c}. Let B = {x.y}. Let C = {0. 1}. List or describe the elements of: C B A In problems 2 & 3 use the following Venn diagram for your answers:

Solution

Sol:

A={1,2,4,5}

B={2,3,5,6}

C={4,5,6,7}

AUBUC=ALL ELEMENTS

={1,2,3,4,5,6,7}

A B C={5} common elements of all the sets

A C={4,5} =common elements of A and C

B C={5,6}=commeon elements of B and C
