Question

Let S be a universal set where S = {1,2,3,4,5,6,7,8,9,10) Let A and B be subsets of S where: A = {2,3,6,7,9,10) and B = {1,2,3,7,8,10)

Find and list all the elements of AUB:

AUB=

Find the cardinality of AUB:

n(AUB)


= Find and list all the elements of AnB:

AnB


= Find the cardinality of AnB:

n(AnB)=


Find and list all the elements of (AnB^C):

(AnB^C) =


here is the picture of the word problems


​

Answer 1

AUB = 1,2,3,6,7,8,9,10

n(AUB) = 8

AnB = 2,3,7,10

n(AnB) = 4
