Question 1155793: defective batteries in a box of 12 batteries, 2 are dead. if 2 batteries are selected at random for a flashlight, find the probability that both are dead. would you consider this event likely or unlikely? Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! probability of first's being dead is 2/12
then second is 1/11
joint probability is product or 2/132 or 1/66. That is less than 2% and would be considered unlikely.
