To solve the problems based on the bar graph, let's analyze the data step by step.

Bar Graph Analysis:

- Red: The bar reaches up to 50 on the vertical axis.
- Yellow: The bar reaches up to 20 on the vertical axis.
- Blue: The bar reaches up to 30 on the vertical axis.
- Orange: The bar reaches up to 30 on the vertical axis.
- Green: The bar reaches up to 10 on the vertical axis.
- Black: The bar reaches up to 40 on the vertical axis.

Problem Solutions:

#### 1. How many students like red?
- From the bar graph, the height of the "Red" bar is at 50.
- Therefore, the number of students who like red is 50.

#### 2. How many students like yellow and blue?
- The height of the "Yellow" bar is at 20.
- The height of the "Blue" bar is at 30.
- To find the total number of students who like yellow and blue, add the two values:
\[
20 + 30 = 50
\]
- Therefore, the number of students who like yellow and blue is 50.

#### 3. How many students are there in the class?
- To find the total number of students in the class, sum the heights of all the bars:
\[
50 \text{ (Red)} + 20 \text{ (Yellow)} + 30 \text{ (Blue)} + 30 \text{ (Orange)} + 10 \text{ (Green)} + 40 \text{ (Black)} = 180
\]
- Therefore, the total number of students in the class is 180.

#### 4. How many students like green, orange, and black?
- The height of the "Green" bar is at 10.
- The height of the "Orange" bar is at 30.
- The height of the "Black" bar is at 40.
- To find the total number of students who like green, orange, and black, add the three values:
\[
10 + 30 + 40 = 80
\]
- Therefore, the number of students who like green, orange, and black is 80.

Final Answers:

1. \(\boxed{50}\)
2. \(\boxed{50}\)
3. \(\boxed{180}\)
4. \(\boxed{80}\)
