A card is drawn from a pack of 52 cards. The probability of getting a queen of club or a king of heart is:
Answer: Option
Explanation:
Here, n(S) = 52.
Let E = event of getting a queen of club or a king of heart.
Then, n(E) = 2.
 P(E) = |
n(E) | = | 2 | = | 1 | . |
| n(S) | 52 | 26 |

In this it has been asking a queen of the club is 1C1,
A king of the heart is 1C1,
Probability = (1C1+1C1)/52C1.
A king of the heart is 1C1,
Probability = (1C1+1C1)/52C1.

The answer is 1/26. The question is what the probability of queen of club & the king of heart. So the queen of the club is only one for that pack of cards. Similarly, the king of the heart is only one So, the total probability is 2.
2/52 = 1/26.
Not mention for club queen and king heart we can use normal method.
2/52 = 1/26.
Not mention for club queen and king heart we can use normal method.

The Probability would be 1/51. The question is from the whole pack of cards & not from only Hearts & clubs, Please clarify 1/26. Thanks,

Here, we can use (13C1/52C1)+(13C1/52C1).

Why is the card name andcolour is specified?

@Sonam.
If we take the probability of getting a queen out of 52 cards is 4/52 and probability of getting King is 4/52. That is why the terms Club and heart are useful.
Probability of draw one card N(S)= 52C1,
Probability of queen of club n(E1)=13C1,
Probability of King of Heart n(E2) =13C1,
N(E) ={n(E1)+n(E2)}/n(S),
N(E) = (13+13)/52,
n(P) =1/26.

N(E) = 1C1 + 1C1 = 1 + 1 = 2.

Answer is 1/13. Because only card is drawn from 52 cards.
