SAT Math Question of the Day

Math Category: Algebraic Sets:

Q: What is the intersection of Set A = {0,2,4,5,9} and Set B = {1,4,6,9}?

  1. {0,1,2,4,5,6,9}
  2. {0,2,4,6,9}
  3. {0,2,5,6}
  4. {4,6}
  5. {4,9}

UNANSWERED.

The correct answer is E.

A: The answer is {4,9}. To find the intersection of 2 sets, you look for what elements are in both sets. Since 4 and 9 are the only elements that are in both Set A and Set B, that is the intersection.
