Five cards—the ten, jack, queen, k | Class 10 Mathematics Chapter Probability, Probability NCERT Solutions

Question:

Five cards—the ten, jack, queen, king and ace of diamonds, are well-shuffled with their face downwards. One card is then picked up at random.
(i) What is the probability that the card is the queen?
(ii) If the queen is drawn and put aside, what is the probability that the second card picked up is (a) an ace? (b) a queen?

Answer:

Total no. Of cards = 5

(i) Number of cards of queen = 1

     Probability of getting a queen = 1/5

(ii) Now, keeping the queen aside only four cards are left

    So,

Total no. of outcome = 4

(a) Number of ace cards = 1

      Probability of getting an ace = ¼

(b) Number of queen cards = 0

      Probability of getting a card of queen = 0/4 = 0
