Q:
A) 9 | B) 14 |
C) 24 | D) 21 |
Answer: A) 9
Explanation:
Explanation:
Given that,
Members in football team = n(f) = 10
Members in science club = n(s) = 14
Members in both football team and science club = n(f ^ s) = 5
Then, Members in only football team = n(F) = 10 - 5 = 5
Members in only science team = n(S) = 14 - 5 = 9
Hence, members in only football or science team = n(FUS) = n(F) + n(S) - n(f^s)
= 9 + 5 - 5
= 9.
Hence, many students belong to only science club team or football team = 9.
