SAT Math Question of the Day

Math Category: Algebraic Sets:

Q: What is the intersection of Set A = {0,1,4,5,8} and Set B = {1,4,6,8}?

  1. {1,4}
  2. {0,5,6}
  3. {1,4,6}
  4. {1,4,8}
  5. {0,1,4,5,6,8}

UNANSWERED.

The correct answer is D.

A: The answer is {1,4,8}. To find the intersection of 2 sets, you look for what elements are in both sets. Since 1, 4 and 8 are the only elements that are in both Set A and Set B, that is the intersection.
