There are 60% of girls in a school. Among them 45% of them are poor. The school is in selection of School People Leader. What is the probability of poor students getting selected?

• Let 100 be the total school strength
  60% of 100 is
  (60/100)*100=60 are girls
  among them 45 are poor
  so,
  45% of 60 is
  (45/100)*60=27 poor girls
  therefore,
  27/60 is the probability of getting selected.
  ans: 9/20

• the question is asking the probability of 'poor students' getting selected and NOT 'poor girls'. All of our solutions are focussed on giving the probability of 'poor girl students' getting selected !
  So, no clue !
  Data insufficient, maybe !

• 27/100
  soln 1:60*45/100=27 so 27/100
  soln 2:60/100*45/100=27/100

• suppose there are 100 student in school
  60% of them are girls =60 girls
  out of 60 45%are poor =27 poor girls
  total student =100
  poor student =27
  prob. of getting a poor leader is 27/100
  (it is not mention that only girls to be chosen as leader we have to include all 100 student ) although ths is incomplete because no data is given about boys may be some of thm are poor

• it is not being asked that probability of selecting a poor girl students out of the total girls . therefore the number of poor students is 27/100= 0.27ans
• 10 years agoHelpfull: Yes(3) No(0)
• Let us assume that the no.of students are 100.
  So, No. of girls=60 and No. of boys=40
  As, (45% of 60) girls are poor i.e. (45/100)*60=27
  Therefore, No. of poor girls=27
  Thus, probability of poor being selected is=27/60
  =9/20

• (60/100)*(45/100)=27/100

• if 100 students are there,
  60 of them are girls
  out of 60 45% of 60 are poor
  (45/100)60=27
  hence probability is 27/100

• both boys and girls is 100%
  60% of girls
  45% of poor
  probability of getting poor 45/100=9/20

• Let 100 be the total school strength
  60% of 100 is=
  60 girls
  among them 45 are poor
  so,
  45% of 60 is
  (45/100)*60=27 poor girls
  therefore,
  27/60 is the probability of getting selected.

• 49/100 let 100 people ...60 girl 40 boy....45% of 60is 27 and 55% of 40 is 22 so 22+27/100=49/100

• 45%(60%of100)/100..
• 10 years agoHelpfull: Yes(0) No(0)
• poor girls=45%
  girls =60%
  total no of students=100%
  
  so, probability of poor girls getting selected is 45/100%
  ie, 9/20%

• it is asking about poor students how the ans can be 9/20. this is the probab for selecting poor girls from total girls.

• I think question should ask for probability of poor girl student not poor studentif poor girl student then answer is 2760920otherwise data insufficient
• 10 years agoHelpfull: Yes(0) No(0)
• Right answer will be 27/100. Because poor girls are selecting from peoples, not from girls.
