In a potato field, the mass of potatoes follows a normal law. If you randomly potatoes here and there, you have a 10% chance of picking a potato with a mass less than 40 grams. Knowing that a potato weighs on average 50 grams, calculate the probability of picking a potato with a mass between 45 and 60 grams.
