Explanation of Solution
Given information:
The total number of students in a survey is
The Venn diagram is,
Explanation:
Let the event
To find the number of students who plan to take physics during their first year. That is,
In the given Venn diagram the number of students who plan to take physics as well as biology or chemistry is also shown. Hence the number of students who plan to take physics during their first year is shown in the following Venn diagram.
Hence, using the Venn diagram find the sum of numbers in the circle drawn for physics.
That is,
Therefore, the number of surveyed students who plan to take physics during their first year is
