Question

From a pack of 52 playing cards, all cards whose numbers are multiples of 3 are removed. A card is now drawn at random. What is the probability that the card drawn is An even-numbered red card? 

Solution 1

The numbers which are multiples of 3 in 52 playing cards are 3, 6, and 9 i.e., 3 cards of each denomination.

∴ All cards whose numbers are multiples of 3 are = 4 x 3 = 12 cards ....(Jack, Queen, and King of each denomination)

Remaining cards = 52 - 12 = 40

Now, Number of face cards = 12

P( even-numbered red card) = `10/40 = 1/4`.

Solution 2

No. of total cards = 52 

cards removed of 4 colours of multiples of 3 

= 3, 6, 9 = 4 x 3 = 12

Remaining cards = 52 - 12 = 40 

An even number red cards = 2, 4, 8, 10 card = 2 x 4 = 8 

⇒ Probability P(E) =`8/40=1/5`

  Is there an error in this question or solution?
