Answer: (1) \(\dfrac{5}{6}\) (2) \(1\)

\(S = \{0, 1, 2, 3, 4, 5\}\), so \(n(S) = 6\).

(1) Natural numbers on the cards: \(A = \{1, 2, 3, 4, 5\}\), \(n(A) = 5\), so \(P(A) = \dfrac{5}{6}\).

(2) Whole numbers on the cards: \(B = \{0, 1, 2, 3, 4, 5\}\), \(n(B) = 6\), so \(P(B) = \dfrac{6}{6} = 1\) (a sure event).
