Your math is incorrect. The total lots of said roles without scrolls is 15 lots. Multiply that by 3 roles to get 45 lots in all for those three roles. But, your three scrolls each add 10 lots to the "lot pool". That equals 75 lots in all for those three roles. Your chances of getting a particular role normally are 1 in 15 since you own 1 in the 15 lots. However, your scroll increases your owned lots by a factor of 10, resulting in a total of 10 out of 25 lots. So, for three roles, you would own 30 out of the 75 lots in all for those three roles. Therefore, evaluating on that fraction (30 out of 75), you have a 40% chance of getting any of those three roles.The key here is to think of the drawings for each scrolled role as a separate, independent event.
