Answer:
1.However, The probability of getting a black card or an ace [which we may denote as P(black or ace)] is not P(black) + P(ace) since the former is 28/52 (there are 26 black cards and 2 red aces) while the latter is 26/52 + 4/52.
2.The total number of cards in pack is 52. ∴ The probability of getting a numbered card is 9/13.
