Q. Two cards are drawn from a well shuffled deck of $52$ playing cards with replacement. The probability, that both cards are queens, is
Probability - Part 2
A
$\frac{1}{13}\times\frac{1}{13}$
71%
B
$\frac{1}{13} + \frac{1}{13}$
9%
C
$\frac{1}{13}\times\frac{1}{17}$
9%
D
$\frac{1}{13}\times\frac{4}{51}$
10%
Solution:
Total number of cards $= 52$
Number of queens $= 4$
Hence, required probability $= \frac{4}{52}\times\frac{4}{52}$
$= \frac{1}{13}\times\frac{1}{13}$
