An engineer must design a control panel for a wind turbine, given the following guidelines:
o Two warning lamps (L1 & L2) turn on when the turbine speed exceeds 5000 rpm (S1)
o If the current through either lamp is stopped (lamp burns out) the other lamp must still be able to illuminate
o The total current must not exceed 0.50 A

A pneumatic system consists of several identical 1.5 inch diameter cylinders to lift 450-pound pallets in a warehouse. The gauge pressure in the system reservoir remains at 75 psi, and the atmospheric pressure is 14.7 psi. Assuming that the weight of the pistons is negligible, determine the total number of 1.5-inch cylinders needed in the pneumatic system to lift the 450-pound load.

A team of students designed a marble sorter to separate a total of 20 marbles into bins. (6 black, 6 blue, and 8 clear) into individual bins. After multiple trials, the students found that the percentage of each color that sorted correctly was as follows: 83% black, 67% blue, and 88% clear.
Given the trial results, what is the theoretical probability that all 20 marbles will be dropped into their corresponding bins during the next run?
1%
10%
48%
62%
