Questions & Step-by-Step Solutions
If 40 students like Mathematics, 30 like Science, and 10 like both, how many students like only Mathematics?
Step 1: Identify the total number of students who like Mathematics, which is 40.
Step 2: Identify the number of students who like both Mathematics and Science, which is 10.
Step 3: To find the number of students who like only Mathematics, subtract the number of students who like both from the total number of students who like Mathematics.
Step 4: Perform the calculation: 40 (students who like Mathematics) - 10 (students who like both) = 30.
Step 5: The result is that 30 students like only Mathematics.
Set Theory – Understanding the relationship between different groups (sets) and how to calculate the number of elements in each subset.
Venn Diagrams – Using Venn diagrams to visualize the overlap between different categories (in this case, students who like Mathematics and Science).
