Problem Solving The correct answer is 2. Let U be the set of all three-digit numbers, let S be the set of three-digit numbers that contain no 2s, and let T be the set of three digit numbers that contain no 3s. Then S ∩T is the set of three-digit numbers containing neither a 2 nor a 3 and U − (S ∪ T) is the set of three-digit numbers containing at least one 2 and at least one 3. We have U = 900, S = T = 8 · 92, and S ∩ T = 7 · 82. Therefore S ∪ T = S + T − S ∩ T = 848, and U − (S ∪ T)= 52. Click here for the next week's Punch |
