Bowl A1 contains 1 red chip and 3 white chips. Bowl A2 contains 3 red chips and 1 white chip. One of the bowls is chosen at random (i. e., each is equally likely), and a chip is withdrawn from that bowl. A) What is probability that the withdrawn chip is red? B) Given that the withdrawn chip is red, what is the probability that bowl A1 was chosen?

The edge of a cube was found to be 30 cm with a possible error in measurement of 0.4 cm. use differentials to estimate the maximum possible error, relative error, and percentage error in computing the volume of the cube and the surface area of the cube. (round your answers to four decimal places.) (a) the volume of the cube maximum possible error cm3 relative error percentage error % (b) the surface area of the cube maximum possible error cm2 relative error percentage error %
