Оптимальные лотерейные билеты, с точки зрения роста достижения:

Всего выбрать 5 из 15 можно 3003 способами.
Суть в том, что для достиги требуется отгадать 4 из 5, поэтому покупая всего один билет, к примеру [1, 2, 3, 4, 5], мы уже покрываем 51 комбинацию, например [1, 2, 3, 4, 6], или [1, 2, 3, 5, 10].
Соответственно покупать их уже смысла нет. На этом и строится мой метод.
Нужна информация по тиражу 01.03.2020
