To see a physical example of non-commuting rotations, do the following experiment. Put a book on your desk and imagine a set of rectangular axes with the x and y axes in the plane of the desk with the z axis vertical. Place the book in the first quadrant with the and y axes along the edges of the book. Rotate the book 900 about the x axis and then 900 about the z axis; note its position. Now repeat the experiment, this time rotating 900 about the z axis first, and then 900 about the x axis; note the different result. Write the matrices representing the 900 rotations and multiply them in both orders. In each case, find the axis and angle of rotation.

Machine A produces 60% of the total items, while Machine B produces 40%. The probability that an item produced by Machine A is defective is P(D|A)=0.03. The probability that an item produced by Machine B is defective is P(D|B) = 0.05. (a) What is the probability that a randomly selected product be defective, P(D)? (b) If a randomly selected item from the production line is defective, calculate the probability that it was produced by Machine A, P(A|D).arrow_forward
