Ответ:

система уравнений для каждой из клеток:

E(1, 1) = 1 + (E(2, 1) + E(1, 2)) / 2

E(1, 2) = 1 + (E(1, 1) + E(2, 2) + E(1, 3)) / 3

E(1, 3) = 1 + (E(1, 2) + E(2, 3)) / 2

E(2, 1) = 1 + (E(1, 1) + E(2, 2) + E(3, 1)) / 3

E(2, 2) = 1 + (E(1, 2) + E(2, 1) + E(2, 3) + E(3, 2)) / 4

E(2, 3) = 1 + (E(1, 3) + E(2, 2) + E(3, 3)) / 3

E(3, 1) = 1 + (E(2, 1) + E(3, 2)) / 2

E(3, 2) = 1 + (E(2, 2) + E(3, 1) + E(3, 3)) / 3

E(3, 3) = 1 + (E(2, 3) + E(3, 2)) / 2
