Ten percent of screws produced in a certain factory turn out to be defective. Find the probability that in a sample of 10 screws chosen at random, exactly two will be defective.
The Equation $$x^3 - x^2 + 4x - 4 = 0$$ is is to be solved using the Newton-Raphson method. If $$x = 2$$ is taken as the initial approximation of the solution, then the next approximation using the method will be
