प्रश्न
From a deck of 52 cards, all the face cards are removed and then the remaining cards are shuffled. Now one card is drawn from the remaining deck. Find the probability that the card drawn is a king of black color.
उत्तर
There are 12 face cards in a deck.
Therefore, possible number of outcomes = 52 – 12 = 40
Since all face cards are removed
Number of favorable outcomes for a king of black color = 0
P(getting a king of black color) = `0/40 = 0`
