Discussion
From a well-shuffled pack of 52 cards, a card is drawn at random, find the probability that it is a spade.
Answer: B
A pack has 13 cards in each of the four suits.
\[ P = \frac{13}{52} = \frac{1}{4} \]
The four suits are equally represented, so each has probability \( \tfrac{1}{4} \) without any counting.
