Câu hỏi: Cho \(A = \left\{ {x \in \mathbb{R}| - 1 \le x < 5} \right\},\,\,\,\,B = \left\{ {x \in \mathbb{R}} \right.|\,\, - 2 < x < 0\)hoặc \(1 < x \le 6{\rm{\} }}\) và  \(C = \left\{ {x \in \mathbb{R}|x \ge 2} \right\}.\)Tìm \(A \cap B,A \cup C,B\backslash C\) ?

A \(A \cap B = \left[ { - 1;2} \right) \cup \left( {2;5} \right),\,\,A \cup C = \left[ { - 1; + \infty } \right),\,\,\,B\backslash C = \left( { - 2;0} \right) \cup \left( {1;2} \right)\)       

B \(A \cap B = \left[ { - 1;0} \right) \cup \left( {1;5} \right),\,\,A \cup C = \left[ { - 2; + \infty } \right),\,\,\,B\backslash C = \left( { - 3;0} \right) \cup \left( {1;2} \right)\)      

C \(A \cap B = \left[ { - 1;2} \right) \cup \left( {1;5} \right),\,\,\,A \cup C = \left[ { - 1; + \infty } \right),\,\,B\backslash C = \left( { - 3;0} \right) \cup \left( {1;2} \right)\)      

D \(A \cap B = \left[ { - 1;0} \right) \cup \left( {1;5} \right),\,\,A \cup C = \left[ { - 1; + \infty } \right),\,\,B\backslash C = \left( { - 2;0} \right) \cup \left( {1;2} \right)\)
