a basket contains 9 apples, of which 1 is spoiled and the rest are good. if we select 2 apples from the basket simultaneously and at random, what is the probability that the 2 apples selected will include the spoiled apple?
divide(choose(subtract(9, 1), 1), choose(9, 2))
the total number of ways to choose 2 apples is 9 c 2 = 36 the number of ways that include the spoiled apple is 8 c 1 = 8 p ( the spoiled apple is included ) = 8 / 36 = 2 / 9 the answer is d .
