Insert ∩ or ∪ to make each statement true. 29. {5,7,9,19}−{7,9,11,15}={7,9} 30. {8,11,15}−{8,11,19,20}={8,11} 31. {2,1,7}−{1,5,9}={1,2,5,7,9} 32. {6,12,14,16}−{6,14,19}={6,12,14,16,19} 33. {3,5,9,10}−∅=∅ 34. {3,5,9,10}−∅={3,5,9,10} 35. {1,2,4}−{1,2,4}={1,2,4}
36. {0,10}−{10,0}={0,10} 37. Describe the intersection and union of sets. How do they differ? 38. Is it possible for two nonempty sets to have the same intersection and union? If so, give an example. Let U={1,2,3,4,5,6,7,8,9},X={2,4,6,8},Y={2,3,4, 5,6}, and Z={1,2,3,8,9}. List the members of each set, using set braces. 39. X∩Y 40. X∪Y 41. X′ 42. Y′ 43. X′∩Y′ 44. X′∩Z 45. Y∩(X∪Z) 46. X′∩(Y′∪Z) 47. (X∩Y′)∪(Z′∩Y′) 48. (X∩Y)∪(X′∩Z) 49. In Example 6, what set do you get when you calculate (A∩B)∪(A∩B′) ?
