Write the number of people who like the color mint.

The correct answer is: 3

Now we know that a graph is made up of vertices, or points, and edges, or lines connecting those vertices. Graphs come in a wide variety of forms in discrete mathematics.
The heights of the rectangular bars in a bar graph, which displays complete data, are proportionate to the values they indicate.
There are two types of a bar graph:

• Vertical Bar Graph
• Horizontal Bar Graph

Although the bars in bar graphs can be plotted either horizontally or vertically, the vertical bar graph is the one that is most frequently used.
Now we have given a bar graph which is a Vertical one. In that graph, there are 5 bars, Vanilla, strawberry, chocolate, mint and toffee. We have asked how many like mint colour.
So from the graph, we can see that the bar of the mint colour is touching the y-axis at 3.
So 3 people like mint colour.

Here we used the concept of bar graphs and understood are different types of bar graphs. The number of people who like the color mint is 3. Although the bars in bar graphs can be plotted either horizontally or vertically, the vertical bar graph is the one that is most frequently used.
