If we assume a bag contains 5000 different apples, these apples are in 10,000 boxes Are:

a) the probability of a blank box? Get an average number of empty boxes.
b) the probability of a box containing 2 apples? Average number of boxes that have 2 apples

I think part of the exercise has been posted only to the subject line, and the text of the exercise may have been translated from another language. Is the meaning perhaps along the lines of the following?



The possibility of a distinctive object within distinctive boxes. Suppose we have five thousand distinct (that is, individually identifiable) apples, and that these apples are distributed amongst ten thousand distinct boxes. Under these conditions, what is:

a) the probability of a given box being empty? (Hint: Find the average number of empty boxes.)

b) the probability of a given box containing two apples? (Hint: Find the average number of boxes which contain two apples.)




If not, please reply with corrections and clarifications. If so, please reply with a clear listing of your thoughts and efforts so far. Thank you! ;)
