there are 3 student organixation (a b and c) in a school.fifty student were asked if they belong to any of these organization and the following data showed:

7 belong to b only
20 belong to c
23 belong to a
5 belong to a and b but not to c
8 belong to a and c but not to b
14 belong to c but not to b
15 belong to a but not to b
assignment sa amin medyo mahirap ehh baka may mali sa problem ehh kaya paggawa daw ng venn diagram
 
Hindi naman ako expert no pero sa tingin ko may kulang:

Sir I suggest if engineering student ka bili ka ng engineering reviewer books ni gillesania at besavilla dapat both bilhin no kasi so gillesania more concept at besavilla more on concept but not enough pero more on kinds of problem

8 belong to a and c but not to b
14 belong to c but not to b
15 belong to a but not to b
tingin ko ito yung mali,
kasi dapat ganito mangyari

Set A has the elements a, d, e and g.
S
et B has the elements b, d, g and f.
Se
t C has the elements e, g, f and c.
Both A and B have the elements d and g.
Both B and C have the elements g and f.
Both C and A have the elements e and g.
A, B and C all have the element g.

Yung sa pagitan ng 20 at 7 ay 6 po yun. Kasi 20-14=6 at sa pagitan ng 23 at 20 ay 8 di ba kasi 23-15=8 make sense di ba ang kulang na lang is yung nasa gitna which is number of students that vote have by organization a,b and c. D nman kasi given number of students. Pano masosolve ung gitna.
 
50 daw, nakalagay sa given hehehe

edit: 50 pala dapat nakalagay dun sa gitna ko hehehe
Panu nyu po nasabi na 50 yun eh d naman given ung total number of students? At saka tama naman ung worded problem pero yun nga kulang ng total number of students.
 
Ts itanung mo sa titser or professor kung ilan ang total number of students. Bibitak ulo mo dto erroneous problem naman to meaning not solvable kasi kulang given. Manapa kung my choices ng mga answer na pagpipilian kayu kong kapain kapag.

ito yung sabi ni ts sa taas:

there are 3 student organixation (a b and c) in a school.fifty student were asked if they belong to any of these organization and the following data showed:

tapos nilagyan ko lang ng data yung diagram base dun sa mga sinabi niyang inputs :)

Kung 50 yun ibig sabihin 50=23+5+7+8+20+6+x, x=-19 meaning mali ang 50 students sa given.
 
nope, ang sabi dun sa introduction ni google
A, B and C all have the element g. G is yung gitna.
A, B, at C, lang ang i-add mo

Hindi 50 ung gitna kasi tanda ko sabi ni sir dindo esplana ung top 1 ng board nung may 2001 ang gitna/center ng Venn diagram ay sumisimbolo sa bagay o tao na kabilang sa lahat ng kategorya na nalaman/surveyed. Meaning ang center ay parte lamang ng total number na nalaman o na survey sa grupo ng mga tao/bagay.

YAN PO ANG TAMANG SAGOT :)

Solution:
7 = B
20 = C + AC + BC + ABC
23 = A + AB + AC + ABC
5 = AB
8 = AC
14 = C + AC
15 = A + AC

15 = A + AC
15 = A + 8
A = 7

14 = C + AC
14 = C + 8
C = 6

20 = C + AC + BC + ABC
20 = 6 + 8 + BC + ABC
BC + ABC = 6 (equation #1)

23 = A + AB + AC + ABC
23 = 7 +5 + 8 + ABC
ABC = 3

from eq#1:
BC + ABC = 6
BC = 6 - 3
BC = 3

youre welcome po.
Note: ung 50 sa problems is ung number ng students na TINANONG. Hindi lahat ng students na tinanong eh kasali sa anumang organization, ung iba walang org, kaya ung total na number ng STUDENTS NA MAY ORG is 39 lang po :) Hindi na po need talaga sabihin ung 39 sa problems since ma solve naman kahit hindi need nun.
