Venn diagrams are pictorial representations of set notations
Represent the event that a student plays tennis with A, and the event that a student is right-handed with B
So, we have the following notations
n(A) = 40%
n(B) = 85%
n(A n B) = 30%
Next, we draw the Venn diagram where the intersection of A and B is represented with 30%
See attachment for the Venn diagram
