प्रश्न
The King, Queen and Jack of the suit spade are removed from a deck of 52 cards. One card is selected from the remaining cards. Find the probability of getting a spade
उत्तर
Total number of cards = 52
3 cards are removed
Remaining number of cards = 52 – 3 = 49
n(S) = 49
Let C be the event of getting a spade card.
n(C) = (13 – 3) = 10
P(C) = `("n"("C"))/("n"("S")) = 10/49`
