Question

find A intersection B.
A: {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}
B: {-2, -1, 1, 4, 7, 11}

{-2, -1, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11}

{1, 4, 7, 11}

{-2, -1, 1, 2, 3, 4, 5, 6}

{ }

Answer 1

Recall what the intersection of two sets means, it means what values do they both have, i'll give you an example if you wanted to find the intersection of these two sets\[(1,2,3,4,5) and (1,3,5)\]then the intersection of those two sets wouldl be\[(1,3,5)\]try to answer yours now with that bit of help

Answer 2

{-2, -1, 1, 2, 3, 4, 5, 6}?

Answer 3

Let me try and rephrase this, you're going to make a new set from the two sets you were given, in this new set, you only want to have values that were in both of the sets A and B, so for instance, they both have the number 1, they both have the number 4, what other numbers do they both have?

Answer 4

7 and 11 so what your doing is picking out the numbers that are boths sets to receive your answer so this one would be 1, 4, 7, 11

Answer 5

?

Answer 6

Yup! nice work, and your explanation was exactly right

Answer 7

cool thanks bro
