A new battery's voltage may be acceptable (A) or unacceptable (U). A certain flashlight requires two batteries, so batteries will be independently selected and tested until two acceptable ones have been found. Suppose that 92% of all batteries have acceptable voltages. Let Y denote the number of batteries that must be tested.
a) What is p(2), that is P(y = 2)?
b) What is p(3)?c) To have Y = 5, what must be true of the fifth battery selected?
i. The fifth battery must be an A.
ii. The fifth battery must be a U.
