A machine shop has 100 drill presses and other machines in constant use. The probability that a machine will become inoperative during a given day is 0.002. During some days, no machines are inoperative, but on other days, one, two, three, or more are broken down. What is the probability that fewer than two machines will be inoperative during a particular day? Select one: a. 0.9824 b. 0.0200 c. 0.1637 d. 0.8187

Race cars go very fast, and they get charged due to friction from the air. This can be a problem when the race car stops for fuel because a spark can go from the car to the fuel dispenser, which is dangerous. So, a race car needs enough time to discharge through its tires before filling it with fuel. Consider a race car that becomes charged such that a potential difference of 30.0 kV is created between the car and the earth. The resistance of each tire of the car is 100.0 G$\Omega$ = 100.0 × $10^9$ $\Omega$ and the metallic body of the car behaves like a 500.0-pF (500.0 × $10^{-12}$ F) capacitor. How long will the car take to discharge through the tires so that the electric potential energy stored in the car body becomes less than $U_{fire}$ = 50.0 mJ? (If the electric energy stored in the car body is more than $U_{fire}$ then there is a high probability a spark results while filling with fuel). One can model the metallic body of the car as a capacitor initially charged to 30.0 kV in parallel with four parallel resistors (each resistor models one tire).
