20 cupcakes are independently put into 5 packages. A is the proabability that one package has 5, one has 3, and the rest have 4 cupcakes. B is the probability that each packages has 4 cupcakes each. What is A/B
I think you misunderstood the problem Guest
If the cup cakes are all identical then I think the answer is 10
I think you have to think of the packets being different, maybe different colours.
There is only 1 way to put four cupcakes in each one.
But there are 5!/3! = 10 ways to put 5,3,4,4,4 cupcakes in them.
I am not certain of my logic but it sounds ok to me.
