Answer
The probability that you will choose a yellow card and then a D card is $\frac{3}{25}$.
Work Step by Step
$ P(yellow)=\frac{3}{5}$
3 of 5 cards are yellow
$P(D-after-yellow)=\frac{1}{5}$
Because you replace the first card, the events are independent.
$P(yellow-then-D)=\frac{3}{5}.\frac{1}{5}=\frac{3}{25}$
The probability that you will choose a yellow card and then a D card is $\frac{3}{25}$.
