Question

Two cards are drawn one by one at random from a pack of $52$ cards. The proabability that both of them are king is

• A. $\frac{2}{13}$
• B. $\frac{1}{169}$
• C. $\frac{1}{221}$
• D. $\frac{30}{221}$

Answer 1

Answer: (C)

$\frac{1}{221}$

Requrid probability is

$\left(\frac{4}{52}\right)\left(\frac{4-1}{52-1}\right)$

$=\frac{12}{52\times 51}$

$\frac{1}{221}=c$
