Question

What is this math symbol and what is it asking me to do?

Answer 1

HI!!

Answer 2

HI :)

Answer 3

that symbol \(\cup\) means "union"

Answer 4

Thanks! Now how do I solve this problem? I don't exactly know what it is asking.

Answer 5

U means union - that is the union of the 2 sets A and B which are illustrated by the circles

Answer 6

So it wants me to find what A + B is minus the center?

Answer 7

A has \(.3\) and B has \(.35\) and they have \(.10\) in common
that means
\[A\cup B=0.30+0.35-0.10\]

Answer 8

yeah exactly A + B minus the center

Answer 9

the center is called \(A\cap B\) reads "A intersect B"

Answer 10

.55 is the answer then, I believe.

Thanks a bunch :)

Answer 11

yes it is \(0.55\)
