Answer 1

(a) 63 is the total strength of students in the school.

Step-by-Step Explanation:

From the question, we have

Basketball= $20$

Football=$10$

Tennis= $18$

Of the above students,

B+F=

F+T= $10$

B+T= $12$

B+F+T= $5$

None= $0$

The venn diagram for this is in the attachment.

Hence, the total number of students in the school is $20+10+18= 63$.
