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.
(18) If the queen is drawn and put aside, what is the probability, that the second card
picked up is an ace.​

Answer 1

Answer:

I) The probability that the card is queen is 1/5

ii) The probability that the card is ace is 1/4

Answer 2

Answer: (i) 1/5 (ii) 1/4

Step-by-step explanation:

(i) Let, the probability of getting a queen be P(A).

There are total 5 cards.

Among them, one card is queen.

Favourable outcomes = 1

Total outcomes = 5

P(A) = favourable outcomes ÷ total outcomes

P(A) = 1/5

The probability of getting a queen is 1/5.

(ii) Let, the probability of getting an ace after the removal of queen be P(B).

There are total 4 cards after the removal of queen.

Among them, 1 card is an ace.

Favourable outcomes = 1

Total outcomes = 4

P(B) = favourable outcomes ÷ total outcomes

P(B) = 1/4

The probability of getting an ace after the removal of queen is 1/4.
