Mehmet wants to meet his childhood love Alev. He has not seen her since they were both ten years old and he wants to impress her by giving a ring to her as a gift. Alev would appreciate (be impressed by) Mehmet if the ring fits her "ring finger". Mehmet doesn't know anything about her finger so he randomly selects a ring from a shop. The diameters of the rings at the shop follows the normal distribution with a mean value of 1.0+(3/10) cm and a standard deviation of 0.4 cm. The diameters of the fingers of 28-year-old-women (Alev's age is 28) in town also have a normal distribution with a mean value of 1.0+(2/10) cm and a standard deviation of 0.8 cm. A ring fits a finger if the diameter of the ring is greater than the diameter of the finger and the difference between these diameters is not greater than 0.2 centimeter. What is the probability that Mehmet will impress her?
