only one
DebbieG
  • DebbieG
Only one is false. But it isn't the 2nd one. \[B \subseteq B\] means that B is either = to, or a subset of, B. That's always true, right? A set is always \(\subseteq \) of itself.

so one sec
DebbieG
  • DebbieG
I don't think so @AkashdeepDeb ... then there would be 2 that are false! ;)
anonymous
  • anonymous
no @AkashdeepDeb thats how it is in the lesson unless you werent speaking to me

∩ whats does this sign mean i forgot

Intersection - It means which elements are common in both
DebbieG
  • DebbieG
Intersection. Anything in the intersection must be in BOTH sets. It's whatever overlaps both.

  • anonymous
i think a
AkashdeepDeb
  • AkashdeepDeb
A is the one that is True. Because A intersection B = {4,8,10} which is B itself!! :D
DebbieG
  • DebbieG
You think a is false? What is in A {intersect} B? (And why can't I find an intersection symbol in the equation editor??)

ok now i get it thanks people for all the help

i just looked at the points wrong i misunderstood what ∩ meant

Answer is C because when we have ∩ they should be like number .

YES! Union is everything in EITHER A or B OR BOTH. :)

then this is union U

U has all circles !

  • DebbieG
here is a silly example I sometimes give my students: think of the "union" of marriage. When my husband and I got married, if I had a toaster, our marriage had a toaster. If he had a toaster, our marriage had a toaster. If we both had toasters, our marriage had (more than 1) toaster. It wasn't necessary, though, that we BOTH had a toaster, for our UNION to have a toaster. Only one or the other. :) I realize it's a very silly example, but hopefully it helps you remember "union". On the other hand, the "intersection" of two streets is ONLY where the streets "overlap".

of course, in general you can't draw one of the circles INSIDE the other. But here you can (and must) because one set is completely contained in the other. There is stuff in A that isn't in B, but nothing in B that isn't in A.

@ :dirtydan667, You can say this picture with the numbers and math languege too !
anonymous
  • anonymous
A can was B but B cant was A
anonymous
  • anonymous
Because A is bigger than B . A says : HAHAHA !!!!

And the smaller is c the bigger ! c
