Alarge bag of marbles contains equal amounts of 5 colors (red, orange, yellow, green, and blue). joaquin selects 1 marble then puts it back and selects another. find the probability of him selecting a yellow marble both times

 The required probability is 4%.

Step-by-step explanation:  Given that a large bag of marbles contains equal amounts of 5 colors, red, orange, yellow, green, and blue. Joaquin selects 1 marble then puts it back and selects another.

We are to find the probability of selecting a yellow marble both times.

Let x number of marbles of each color is present in the bag.

Let S be the sample space for the experiment of selecting a marble from the bag.

n(S) = x + x + x + x + x = 5x.

Now, let A denote the event of selecting a yellow marble.

Then, n(A) = x.

Since the second marble is drawn after replacing the first one, so the probability of selecting a yellow marble both times is given by

Thus, the required probability is 4%.
