A basket contains 8 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?
Answer/Solution
1/4
Steps/Work
The total number of ways to choose 2 apples is 8C2 = 28
The number of ways that include the spoiled apple is 7C1 = 7
P(the spoiled apple is included) = 7/28 = 1/4
The answer is C.
The number of ways that include the spoiled apple is 7C1 = 7
P(the spoiled apple is included) = 7/28 = 1/4
The answer is C.
