![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 95% 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) = 0.9025
(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) = 0.090
(c) To have Y = 5, what must be true of the fifth battery selected?
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.)
{UUUAA, UAUUA,UUAUA AUUUA}
Determine p(5). (Round your answer to five decimal places.)
p(5) = 0.00045
