$P\left(A|B\right)=\dfrac{P\left(A\right)}{P\left(B\right)}$

$P\left(A|B\right)=\dfrac{P\left(A\right)}{P\left(AB\right)}$

$P\left(A|B\right)=\dfrac{P\left(AB\right)}{P\left(B\right)}$

$P\left(A|B\right)=\dfrac{P\left(AB\right)}{P\left(A\right).P\left(B\right)}$

$P\left(A\right)=P\left(B\right).P\left(A|B\right)+P\left(\overline{B}\right).P\left(A|\overline{B}\right)$

$P\left(A\right)=P\left(\overline{B}\right).P\left(A|\overline{B}\right)-P\left(B\right).P\left(A|B\right)$

$P\left(A\right)=P\left(B\right).P\left(A|B\right)-P\left(\overline{B}\right).P\left(A|\overline{B}\right)$

$P\left(A\right)=P\left(\overline{B}\right).P\left(A|\overline{B}\right)+P\left(B\right).P\left(A|\overline{B}\right)$

x + 2y - 2z + 3 = 0

x - 2y - 2z - 1 = 0

x - 2y + 2z - 12 = 0

x - 2y + 2z - 6 = 0. B. TRẮC NGHIỆM ĐÚNG - SAI. Thí sinh trả lời từ câu 1 đến câu 2. Trong mỗi ý a), b), c), d) ở mỗi câu, thí sinh chọn đúng hoặc sai
