ResponderExcluirO espaço amostral deste experimento é:
U = {(1, 1), (1, 2), (1, 3), (1, 4), (1, 5), (1, 6),
(2, 1), (2, 2), (2, 3), (2, 4), (2, 5), (2, 6),
(3, 1), (3, 2), (3, 3), (3, 4), (3, 5), (3, 6),

(6, 1), (6, 2), (6, 3), (6, 4), (6, 5), (6, 6)}.
Logo, n(U) = 36.
Soma 7 → A = {(1, 6), (2, 5), (3, 4), (4, 3), (5, 2), (6, 1)} → n(A) = 6
P(A) = 6/36 = 1/6
