1M 1M 1M 25 Given lines are If the lines are coplanar then 1M Hence the lines are coplanar. 1½ M Equation of the plane containing the lines is 1M is the required equation to the plane 1½ M 1M 26 The probability of success is twice the probability of failure. Let the probability of failure be x. Probability of success = 2x ∴ 1 M
