Answer

The correct answer is — Step 5: State the final probability as (rounded to four decimal places).

Step-by-step solution

  1. Step 1: Compute the probability that the first card drawn is a spade: .
  2. Step 2: After drawing a spade, 51 cards remain, of which 13 are hearts.
  3. Step 3: Compute the conditional probability that the second card is a heart: .
  4. Step 4: Multiply the probabilities of the two independent steps: .
  5. Step 5: State the final probability as (rounded to four decimal places).
Common mistake: Treating draws as independent and using for the second draw

Concept tested: Conditional probability without replacement
