Previous Question: Let (x, y, z) be points with integer coordinates satisfying the system of homogeneous equations: 3x - y - z = 0 -3x + z = 0 -3x + 2y +z = 0. Then the number of such points for which x^2 + y^2 + z^2 = 100 is Next Question: An experiment has 10 equally likely outcomes. Let A and B be two non-empty events of the experiment. If A consists of 4 outcomes, the number of outcomes that B must have so that A and B are independent, is? a) 3,6,or 9 b) 2,4 or 8 c) 5 or 10 d) 4 or 8
