Solution:
D. $2 / 13$
REASON:
A deck of cards is given.
Let X be the total number of aces you’ve gotten.
Therefore Expectation of $\mathrm{X} \mathrm{E}(\mathrm{X})$
$\mathrm{E}(\mathrm{X})=\sum_{\mathrm{i}=1}^{\mathrm{n}} \mathrm{x}_{\mathrm{i}} \mathrm{p}_{\mathrm{i}}$
$=0 \times \frac{1128}{1326}+1 \times \frac{192}{1326}+2 \times \frac{6}{1326}$
$=\frac{204}{1326}$
$\Rightarrow \mathrm{E}(\mathrm{X})=\frac{2}{13}$
As a result, the correct answer is (D).
