If X = {x : x < 7} and Y = {y:y is a factor of 24} are subsets of \(\mu\) = {1, 2, 3...10} find X \(\cap\) Y.

  • A {2, 3, 4, 6}
  • B {1, 2, 3, 4, 6}
  • C {2, 3, 4, 6, 8}
  • D {1, 2, 3, 4, 6, 8}

The correct answer is B. {1, 2, 3, 4, 6}

\(\mu\) = {1, 2, 3, 4..., 10}

X = {1, 2, 3, 4, 5, 6}

Y = {1, 2, 3, 4, 6, 8}

Therefore;

X \(\cap\) Y = {1, 2, 3, 4, 6}
