We are asked to express the shaded area as a fraction, a decimal, and a percent of the whole.
We can see that in our figure there are 100 squares as there are 10 rows and each row contains 10 squares.
We can also see that there are 81 shaded squares out of 100 squares, so we can represent it as a fraction as:

Step-by-step explanation:
We can see these two events are independent as Regina replaced marble after drawing one marble.
We can find possible outcomes by adding number of blue, red and yellow marbles.
possible outcomes= 4+3+10= 17
Let us find probability of getting a blue marble on first draw.
Now we will find probability of getting red marble.
We can find probability of getting a blue marble and then red marble by multiplying both probabilities.
