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 black card.
उत्तर
There are 12 face cards in a deck.
Therefore, possible number of outcomes = 52 – 12 = 40
Number of favorable outcomes for black cards = 26 cards – 6 face cards = 20
P(a black card) = `20/40 = 1/2`
