Question

Five cards-ten, jack, queen, king, and an ace of diamonds are shuffled face downwards. One card is picked at random. If a king is drawn first and put aside, what is the probability that the second card picked up is the king?

Answer 1

Total cards initially: 5 (ten, jack, queen, king, ace of diamonds)

When a king is drawn and put aside:

Remaining cards: 4 (ten, jack, queen, ace)

Total possible outcomes: \[n(S') = 4\]

A king:

Number of kings remaining: 0

Probability: \[P(\text{King}) = \dfrac{0}{4} = 0\]
