You order twelve burritos to go from a mexican restaurant, five with hot peppers and seven without. however, the restaurant forgot to label them. if you pick three burritos at random, find the probability that none of them have hot peppers. (round the answer to three decimal places.)

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 %
