In a Mathematics test, the following marks were obtained by 40 students. Arrange these marks in a table using tally marks.(a) Find how many students obtained marks equal to or more than 7.(b) How many students obtained marks below 4?

Explanation

To solve the problem step by step, we will first organize the marks obtained by the 40 students into a tally mark table, then answer the two parts of the question.

### Step 1: Create a Tally Mark Table

1. **List the Marks**: We need to identify the marks obtained by the students. Let's assume the marks are as follows (you can replace this with the actual data if provided):
- 1, 1, 2, 2, 3, 3, 3, 4, 4, 5, 5, 6, 6, 6, 7, 7, 7, 7, 7, 8, 8, 8, 8, 9, 9, 9

2. **Count the Frequency**: Count how many times each mark appears.
