Anew battery’s voltage may be acceptable (a) or unacceptable (u). a certain flashlight requires two batteries. batteries will be independently selected and tested until the flashlight turns on. suppose that 90% of all batteries have acceptable voltages. let y denote the number of batteries that must be tested. a. what is p(2)? b. what is p(3)? [hint: there are two outcomes that result in y=3] c. to have y = 5, what must be true of the fifth battery selected? list the four outcomes for which y=5 and then determine p(5).
