Two cards are drawn successively with replacement from a well shuffled pack of 52 cards. The mean of number of kings is
  1. $\frac{4}{169}$
  2. $\frac{1}{13}$
  3. $\frac{1}{169}$
  4. $\frac{2}{13}$

Solution

Here, $n=2, p=\frac{1}{13}$ and $q=\frac{12}{13}$ Mean, $n p=2 \times \frac{1}{13}=\frac{2}{13}$
