16 students play all the sports.
3) How many students are there in the class
4) How many students play only cricket.

• 
  total no. of students
  = n(B U T U C)= n(B)+n(T)+n(C)-n(B∩T)-n(B∩C)-n(C∩T)+n(B∩T∩C)
  = n(B U T U C)= 73+79+75-25-24-30+16
  = n(B U T U C)= 164
  
  students play only cricket =
  only n(c) = n(C)- n(T U C) - n(B U C)+ n(T ∩ B ∩ C) = 75-24-30+16 = 37

• N(BUTUC)=N(T)+N(B)+N(C)-N(B∩T)-N(B∩C)-N(C∩T)+N(B∩T∩C)
  N(BUTUC)=73+79+75-25-30-24+16
  Total Students :N(BUTUC)=164
  PERSONS PLAY CRICKET ONLY=N(C)-N(B∩C)-N(C∩T)-2(N(B∩T∩C))
  =75-30-24-(2*16)
  =37

• can u please explain it through venn diagrams
• 10 years agoHelpfull: Yes(2) No(1)
• (73+75+79)-2(30+16+25)-32 = 37
• 10 years agoHelpfull: Yes(0) No(1)
• total student : 73+79+75-24-25-30+16 = 164
  
  students play only cricket : 75-24-30+16 = 37

• total no. of students
  = n(B U T U C)= n(B)+n(T)+n(C)-n(B∩T)-n(B∩C)-n(C∩T)+2*n(B∩T∩C) (as we have included B T & C 3 times so we have to sub it 2times)
  = n(B U T U C)= 73+79+75-25-24-30+32
  = n(B U T U C)= 180
  
  second one is easy 37

• ans:126
  No of students who plays only table tennis is :8
  No of students who plays only batmen-ton is :8
  No of students who plays only cricket is :15
  so total number of students are:8+8+15+25+24+16+30
