In Exercises 21–28, find the intersection of the sets. {1,2,3,4}∩{2,4,5}

Accepted Answer

Hello. Today we're going to be finding the intersection between two sets of numbers. So I'm gonna go ahead and label the first set as set A. And the second set of numbers. I'm gonna label as set B. And I'm just gonna go ahead and list out the terms of every set. So for set a. The terms are 48, 12 and 15. And for set be the terms are 11, 12, 25 and 15. Now the intersection between these two sets of numbers is going to be a set of numbers that only involves the common terms between our two sets a. And b. So we need to identify the common terms between our two sets. Well, those common terms are going to be 12 And it's going to be 15. So the intersection Of A. & B. is going to be the set of numbers involving 12 and 15. And this is going to be our solution. And the answer to this problem is going to be C. So I hope this video helps you in understanding how to find the intersection of two sets. And I'll go ahead and see you all in the next video.
