From a pack of 52 cards, two cards are drawn together at random. What is the probability of both the cards being kings?
- A. 1/(15)
- B. 25/(57)
- C. 35/(256)
- D. 1/(221)
✅ Correct Answer: 1/(221)
Explanation
Let S be the sample space. Then, n(S)=^(52)C_(2)=(52 x 51)/((2 x 1))=1326. Let E=event of getting 2 kings out of 4. [https://www.indiabix.com/_files/images/aptitude/1-sym-tfr.gif] n(E)=^(4)C_(2)=(4 x 3)/((2 x 1))=6. [https://www.indiabix.com/_files/images/aptitude/1-sym-tfr.gif] P(E)=n(E)/(n(S))=
