Answer:

Stayed the same

Step-by-step explanation:

Altogether, there are 8 marbles in the bag (before Keenan adds the other marbles.) The probability so far that he draws a yellow marble is 4/8, or 1/2.

When he adds the marbles to the bag, there are 10 marbles altogether and 5 yellow marbles. The probability now is 5/10, or 1/2.

The probability has stayed the same.

P(y) = 5/10 = 1/2

<em>Answer: Stays the same</em>
