A card is drawn at random from a well-shuffled deck of playing cards. What is the probability of getting a face card of black colour?
Answer
The correct answer is — Calculate the probability using .
Step-by-step solution
- Identify the total number of possible outcomes: a standard deck has playing cards, so .
- Identify the favorable outcomes: face cards are Kings, Queens, and Jacks. There are black suits (Spades and Clubs), so the total number of black face cards is .
- Calculate the probability using .
Common mistake: Counting all 12 face cards instead of only the 6 black face cards.
