1. A bag contains red, blue, green, and yellow marbles. Seth takes a marble from the bag without looking, records the color of the marble, and then puts the marble back in the bag. He repeats the process until he has recorded the colors of 35 marbles. The chart below shows the results of his experiment.

To find the total number of marbles, you need to add up the number of marbles of each color. In this case, Seth recorded the following colors and quantities: red (10), blue (5), green (13), and yellow (7). To find the total, simply add up these numbers:

10 + 5 + 13 + 7 = 35

Therefore, Seth recorded the colors of 35 marbles in total.
