Nuclear power plants have redundant components in important systems to reduce the chance of catastrophic failure. assume that a plant has two gauges to measure the level of coolant in the reactor core and that each gauge has probability 0.01 of failing. assume that one potential cause of gauge failure is that the electric ca- bles leading from the core to the control room where the gauges are located may burn up in a fire. someone wishes to estimate the probability that both gauges fail, and makes the following calculation: p (both gauges fail) = p (first gauge fails) p (second gauge fails) = (0.01)(0.01) = 0.0001 what assumption is being made in this calculation? explain why this assumption is probably not justi- fied in the present case. a. b. c. is the probability of 0.0001 likely to be too high or too low? explain.

Aball is tied to the end of a length of string. a student holds one end of the string and whirls it so the ball travels in a vertical circle. first she whirls the ball at a very fast speed, and then she very gradually lowers the speed. where is the ball most likely to be when the string begins to sag? a.) at the top of the circle b.) descending at the midway point between the top and bottom of the circle c.) ascending at the midway point between the top and bottom of the circle d.) at the bottom of the circle
