VENN DIAGRAM, TYPES OF VENN DIAGRAMS(1-5), TYPES OF VENN DIAGRAMS - Coggle…

- - - - whenever neither is given for an element we should not consider it
      - neither tea and coffe
        
        means who dont drink both tea and coffee as well
    - - whenever either is given we should consider both values
      - ex: either A or B means it can be in A and it can be in B , it can be common in both A and B
    - - either (or) both hold same meaning
      - both A and B mean
        
        we can pick all values in A
        
        we can pick all values in B
        
        we can also pick common values in both A and B
    - - we should pick a value which is present only in A and this value should not be common in B or C , it should belong only to A
    - - since not in C is mentioned, we can simply strikeoff c
      - and since only A and B is mentioned, we should pick only common value b/w A and B
    - - pick a value which is present only in A, means it should not be common in C
      - we can simply strike off B
    - - we can completely stike off C
      - pick all values in A, all values in B , also pick common values in both A & B
- - - - in above figure he gave rural dia, stu dia, intelligent and combining all 3 dia he gave a venn dia
      - and he asked rural students who are not intelligent
        
        since not intelligent is asked we can simply sticke off intelligent box
        
        and pic someone who is common in both rural and stu dia
      - go through keywords above, they will be useful here also
  - - - we have 2 elements here A, B
      - formulas for 2 set ven dia
        
        people who drink only A = a
        
        people who drink only B= b
        
        1set
        
        as they drink exactly one drink !.e not lessthan 1 or greater than 1 exactly 1. so, 1 set
        
        1set= a+b
        
        1.people who drink A= a, c
        
        people who drink B = b, c
        
        people who drink only A&B = c
        
        2set
        
        as they drink exactly 2
        
        2set= c
        
        8.atleast 1
        
        atleast means min to max
        
        since atleast1 is given min should start from set and go to max sets that we have
        
        atleast1 = set1+ set2
        
        a+b+c
        
        atleast2
        
        set2
        
        since atleast2, it starts with set2 and we dont have greater set than it formula ends there
        
        atleast2 = c
        
        atmost1
        
        atmost means max to min
        
        since atmost1, it should start from set1 and followed by its decreasing values
        
        atmost1 = set1 + null
        
        a+b+n
        
        atmost2
        
        set2 + set1+ null
        
        c+a+b+n
        
        total= a+b+c+null
        
        null = people who dont like A & B, or people who dont come under A & B
- - - - if this 4 sta are valid and logical them only our venn dia is correct
- - - - all apples are fruits
    - - some fruits are apples
- - - - some men are doctors
      - some doctors are men
    - - some doctors are women
      - some women are doctors
- - - - ex: all india lies in asia
  - - - ex: all pakisthan lies in asia
  - - - some part of asia ia india
  - - - if both of this sta are fullfilles then only we can say given dia is correct or given ste belongs to this [arti venn dia
- - - - some actors are politicians
      - some politicians are actors
    - - some politicains are doctors
      - some doctors are politicians
    - - some doctors are actors
      - some actors are doctors
