In A Class Of 60 Students, 30 Offer Physcis And 40 Offer Chemistry, (a)Use Venn Diagram To Represent This Information (b) How Many Students Offer Both Subject. find the number of those that offered history only, the number that offered economics only, the number of student that offered literature only
so, did you make the diagram?
If x take both, then 30+40-x = 60
assuming everyone took something.
To represent this information using a Venn diagram, follow these steps:
Step 1: Draw a rectangle to represent the entire class of 60 students.
Step 2: Label one circle as "Physics" and the other circle as "Chemistry" inside the rectangle.
Step 3: Inside the "Physics" circle, write "30" to represent the number of students offering Physics.
Step 4: Inside the "Chemistry" circle, write "40" to represent the number of students offering Chemistry.
Now, let's find the number of students who offer both subjects:
To find the number of students who offer both Physics and Chemistry:
Step 5: Find the intersection of the two circles, where they overlap.
Step 6: Inside this intersection area, write the number of students who offer both subjects.
To find the number of students who offered only History, follow these steps:
Step 7: Outside the "Physics" and "Chemistry" circles, but inside the rectangle, write the number of students who offered only History.
(Note: We do not have information about the number of students who offered History, so we cannot determine this number).
To find the number of students who offered only Economics:
Step 8: Outside the "Physics" and "Chemistry" circles, but inside the rectangle, write the number of students who offered only Economics.
(Note: We do not have information about the number of students who offered Economics, so we cannot determine this number).
To find the number of students who offered only Literature:
Step 9: Outside the "Physics" and "Chemistry" circles, but inside the rectangle, write the number of students who offered only Literature.
(Note: We do not have information about the number of students who offered Literature, so we cannot determine this number).
Unfortunately, without additional information, we cannot accurately determine the number of students who offered History, Economics, or Literature only.
