Among 60 apples collected from an apple tree, there are three bad apples. The apples are randomly placed into four baskets so that each basket contains 15 apples.
Compute the probability that the three bad apples are not all in the same basket.
Can anyone confirm if my method is right?
I then need to find the probability that no two bad apples are in the same basket, in other words each bad apple is in a different basket. How do I do this one?
