Best answer

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

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

(1) Natural numbers start from 1, so 0 is not included. A = {1, 2, 3, 4, 5}, n(A) = 5, \(P(A) = \dfrac{5}{6}\).

(2) Whole numbers include 0, so every card qualifies. B = {0, 1, 2, 3, 4, 5}, n(B) = 6, \(P(B) = \dfrac{6}{6} = 1\). This is a sure event.
