Question:medium

Two cards are drawn randomly from a pack of 52 playing cards one after the other with replacement. If A is the event of drawing a face card in the first draw and B is the event of drawing a clubs card in the second draw, then $P\left(\frac{B}{A}\right)=$

Show Hint

The keywords "with replacement" are crucial in probability problems involving sequential draws. They almost always signify that the events are independent. For independent events A and B, remember that $P(A|B) = P(A)$ and $P(B|A) = P(B)$.

  • $\frac{11}{12}$
  • $\frac{12}{13}$
  • $\frac{3}{4}$
  • $\frac{1}{4}$
Show Solution

The Correct Option is D

Solution and Explanation

Step 1: Check for Independence: Since the cards are drawn with replacement, the outcome of the second draw is independent of the first. Thus, \( P(B|A) = P(B) \).
Step 2: Calculate Probability of B: Event B is drawing a clubs card. There are 13 clubs in a deck of 52 cards. \[ P(B) = \frac{13}{52} = \frac{1}{4} \] Therefore, \( P(B|A) = \frac{1}{4} \).
