Розглянемо \textbf{10} бульових змінних \textbf{x_1},\textbf{ x_2},\textbf{ x_3},\textbf{ x_4},\textbf{ x_5},\textbf{ x_6},\textbf{ x_7},\textbf{ x_8},\textbf{ x_9} та \textbf{x_10}. Розглянемо усі можливі пари та трійки різних змінних із цих десяти (усього існує \textbf{45} пари та \textbf{120} трійки). Обчисліть кількість пар та трійок, у яких хоча б одна змінна встановлена в \textbf{1}. Покладемо \textbf{f(x_1, x_2, x_3, x_4, x_5, x_6, x_7, x_8, x_9, x_10)} = \textbf{1} якщо ця кількість непарна і \textbf{f(x_1, x_2, x_3, x_4, x_5, x_6, x_7, x_8, x_9, x_10)} = \textbf{0} якщо кількість парна. Розглянемо явну формулу, яка реалізує функцію \textbf{f(x_1, x_2, x_3, x_4, x_5, x_6, x_7, x_8, x_9, x_10)}:
