Answer:
Blue: 2, Red: 8, Yellow: 5, Green: 9
Step-by-step explanation:
If you read the y-axis/left side of the graph where it says digits, wherever the bar ends, that is the digit. For example, the blue bar ends at 2 in the digits on the left. So the digit is 2. And the yellow bar ends at 5 on the left side (even though there is no 5, we can assume that since the number is in between 6 and 4, the number is 5.) so the digit would be 5.
