Find A U B and explain what that number represents.

Find A′ and B′and explain what that number represents.

Which word would you use to describe the value of v in the Venn diagram: subset, union, intersection, complement, or cross multiplication product? Explain your answer in complete sentences.

Answer 1

we need to know what is in A and B (they should be sets of numbers or objects)

Answer 2

in the second one it is a upside U

Answer 3

A U b is 10

Answer 4

A U B is {6, 4, 1}

Answer 5

A U B means the union of sets A and B. so this means LIST EVERYHTING IN SETS A and SETS B.

Answer 6

hey moyo but we dun include intersection point

Answer 7

for the second one (upside down U) this means intersection. so the intersection of the two sets is WHAT IS IN BOTH OF THE SETS A and B?

the answer for that one would be the 1. it's the only number in both A and B.

Answer 8

yes we do because 1 is in A, and also 1 is in B. so we have to include it.

Answer 9

coral, is that a ONE in the middle?

Answer 10

yes it is a one in the middle

Answer 11

a)11 represents the total number present in both sets
b)1 represent the numbers which are not in both of these sets

Answer 12

you don't need to ADD the numbers. you have to LIST them in parentheses/brackets. they are objects in a set!!

Answer 13

A U B is {6, 4, 1}

Answer 14

ohhh ok thanks

Answer 15

A' i think means "stuff that's NOT in A"

so in this case, the stuff not in A = {4} (assuming A is the circle on the left, and B is the one on the right)

Answer 16

B' = {6}

Answer 17

i don't see a V in your diagram coral...
