Find batteries tested until finding two acceptable ones

Reference no: EM13115596

New battery's voltage may be acceptable or unacceptable. A certain flashlight requires 2 batteries, so batteries will be independently selected and tested until 2 working ones are found. Assume that 89 percent of all batteries have acceptable voltages. Let Y be the number of batteries that must be tested until finding two acceptable ones. What is the probability that Y=6?
