You want to remind me oo/oo=oo?

If you think changing is better,that's OK.If this case you try 100 times you get 55x,I don't change also get 55x.If you think a lot,it is because you always think you get x,in fact,some times you get 10x.When you think clear it is simple.We know the Prob.theory had relation with gambling 400 years ago.If you have oo money,you can earn oo,in your case.Certainly,we use given N find n do it. But nobody can do for big N.There is no paradox.oo/oo =oo that's OK,but no real meaning.
