Trong không gian cho 4 điểm không đồng phẳng. Có thể xác định được bao nhiêu mặt phẳng phân biệt mà mỗi mặt phẳng đi qua ba trong bốn điểm đã cho? 4. 2. 3 1.

The correct answer is .To determine a plane in space, we need at least three non-collinear points. Since we have four non-coplanar points, we can choose any three of them to define a unique plane. The number of ways to choose 3 points from 4 is given by the combination formula:C(4,3) = 4! / (3! * 1!) = 4Therefore, there are 4 distinct planes that can be determined from the four non-coplanar points.
