Question

If A = {2, 4, 6, 8, 10…} and B = {1, 3, 5, 7, …}, what is A ∩ B?
HELP!!

Answer 1

what do the two sets have in common?

Answer 2

what number or numbers are in both sets at the same time?

Answer 3

Uhh...None of themm...

Answer 4

that's correct, set A is the set of even numbers while set B is the set of odd numbers

a number is either even or odd and cannot be both at the same time

so the two sets have NOTHING in common, which means that the intersection of sets A and B is the empty set

Answer 5

A ∩ B = empty set

which is a mathematical way to say that they share nothing in common

Answer 6

So is it only the brackets? for the answer?

Answer 7

yes, one way to say "empty set" is to write { }

Answer 8

or writing a O with a slash through the O is another way to say "empty set"
