The probability of selecting two orange marbles with replacement is 36/169.

Data;

<h3>Probability with replacement</h3>

Since after each draw, the orange marble is replaced.

The total number of marbles in the bag is

6+3+4 = 13

And the number of orange marbles is 6.

For the first selection, the probability of selecting one orange is

$P = \frac{6}{13}$

After drawn and replaced, the probability of selecting another marble is

$P = \frac{6}{13}$

And the probability of selecting two orange marbles with replacement is

$P = \frac{6}{13} * \frac{6}{13} = \frac{36}{169}$

The probability of selecting two orange marbles with replacement is 36/169.
