Anyone good at math :-P

Given the sets: A = {5, 10, 15, 20, 25}, B = {3, 6, 9, 12, 15} http://www.omegamath.com/scripts/elementary/Etest/image5818.gif

First off what is this upside down U, and how do i find the answer lol.
i have 4 options to answer from here they are.
A. { }
B. {3 ,5, 6, 9, 10, 12, 25}
C. {3, 5, 6 ,9, 10, 12, 15, 25}
D. {15}

Anyone know what the answer is :-P because me

 

Never heard of Set Theory?? Upside down U LMAO.....

The Upside Down U is called Intersection that means-
x is an element of A ∩ B if and only if

* x is an element of A and
* x is an element of B.

If given the sets are
A = {5, 10, 15, 20, 25}, B = {3, 6, 9, 12, 15}
the Answer would be
A ∩ B = {15}
Option D

 

what math class are you in? haha

 

Ummm....Who??

 

the answer is D. {15}

 

the person who made this thread

 

haha... to tell you the truth... im reall confuse with U and ∩... haha...

if im not mistaken the symbols above are the universal sign (or something) and the intersection sign...

 

U - Union

∩ - Intersection

 

It's basically, which number is in group A and B.

bah already answered

 

Jhaggas! Webby is hot when he turns into a Mathematical nerd.

Indian's may be tharki, but they sure are clever mo'fos.

 

Thanks Mella , I am an engineer by education so Math is my other life.

Well I am not tharki
