Ninety-five percent of light incident on a mirror is reflected. How much light is reflected from three mirrors in succession?

Three resistors take the shape of a triangle, one resistor in each leg. Resistance in one leg is 4 ohms, in a second leg is 6 ohms, and third leg is 10 ohms. A measurement of resistance across the 10-ohm resistor will show the equivalent resistance to be
