Given : number of students in three sports clubs

Football

Basketball

Cricket

Total = 1000 students

To Find  :

Football only

Cricket only

Basketball but not in football

Students not in any club

Solution:

F = 50

B = 100

C= 80

F∩ B = 20

F∩ C = 10

B ∩ C = 15

F∩ B  ∩ C = 0

Football only

F - F∩ B - F∩C + F∩B∩C  = 50 - 20 - 10 + 0  = 20

Cricket only

C - F∩ C - B ∩ C  + F∩B∩C  = 80 - 10 - 15 + 0  = 55

Basketball but not in football

B - F∩ B = 100 - 20  = 80

Total = F + B + C -  F∩ B  - F∩ C - B ∩ C  + F∩B∩C + None

=> 100 = 50 + 100 + 80 - 20 - 10 - 15 + 0 + None

=> None = 815

Students not in any club = 815

13 = 5 + 10 -  liked by both

=> liked by both = 2

(1001)₂ =  1* 2³ +  0 * 2²  + 0 * 2¹  + 1 * 2⁰   = 9

(11110)₂ =  1*2⁴ + 1* 2³ + 1 * 2²  + 1 * 2¹  + 0 * 2⁰   = 30
