Explanation of Solution
Given information:
The total number of students in a survey is
The Venn diagram is,
Explanation:
The total number of students in a survey is
First find the number of surveyed students who plan to take biology, chemistry, or physics during their first year. That is,
Hence, using the Venn diagram find the sum of all numbers in the circles drawn for biology, chemistry and physics.
That is,
Hence, the number of surveyed students who do not plan to take biology, chemistry, or physics during their first year is,
Therefore, the number of surveyed students who do not plan to take biology, chemistry, or physics during their first year is
