Final answer:
The probability of drawing the queen of spades from a well-shuffled standard deck of 52 cards is 1/52.
Step-by-step explanation:
The question asks about the probability of drawing the queen of spades from a well-shuffled deck of 52 playing cards. In a standard deck, there is only one queen of spades.
To find the probability, we can count the favorable outcomes over the total number of possible outcomes. Since there is just one queen of spades and 52 cards in total, the probability is 1 out of 52, or ⅓.
Therefore, the correct answer is (a) ⅓.
