Respuesta :

Answer:

1/4

Step-by-step explanation:

There are 2 yellow, 3 red and 5 blue for a total of 10 marbles.

The probability  of drawing a blue marble is 5/10 = 1/2

If the marble is replaced, then there are 10 marbles in the bag.

So, the probability of drawing another blue marble is 1/2

Now, multiply the two probabilities together to get the final probability.

1/2(1/2) = 1/4
