Question
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 91% 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)? (Round your answer to four decimal places.)
p(2) =
(b) What is p(3)? [Hint: There are two different outcomes that result in Y = 3.]. (Round your answer to three decimal places.)
p(3) =
(c) To have Y = 5, what must be true of the fifth battery selected?
O The fifth battery must be an A.
O The fifth battery must be a U.
List the four outcomes for which Y = 5. (Enter your answer in set notation.)
Determine p(5). (Round your answer to five decimal places.)
p(5) =
(d) Use the pattern in your answers for parts (a)-(c) to obtain a general formula for p(y).
