Edward has four pearls – two white and two black – which he can distribute as he chooses between two identical bags. He must the
n choose a bag at random and pick one pearl at random from the bag he chose. If Edward distributes the pearls so as to maximize his chances of picking a black pearl, what is the probability that Edward will pick a black pearl?
We know (Ohm second law) that where k inlcudes the rest of the parameters (material, lenght). In our situation we have k= . The moment the diameter becomes 8mm R becomes
