A box of 50 socks contains three colors of socks: blue, white, and black. There are at least 10 socks of each color. Robyn chose a sock at random 100 times, replaced the sock each time, and calculated the probability of choosing a blue sock. The next day, Robyn did the same experiment again. This time, the probability of choosing a blue sock was very different. What most likely happened to greatly change the probability of selecting a blue sock?

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 %
