There is a school were 60% are girls and 35% of the girls are poor.
Students are selected at random, what is the probability of selecting a poor girl out of total strength.

• '21 will be the probability of poor girl out of total strength....
  
  let 100 be the total strength
  60% out of 100= 60 number of girls
  now 35% of gals are poor ..i.e. (35/60)*100 are poor girl=21
  
  so 21% of total strength are poo... i.e. the probability is .21

• 21 will be the probability of poor girl out of total strength....
  
  let 100 be the total strength
  60% out of 100= 60 number of girls
  now 35% of girls are poor ..i.e. (35/100)*60 =21
  therefore probability of selecting a poor girl out of 21 poor girls is 21 c 1=21

• let the total school strength be 100
  60%(100)=60 students are girl students
  35%(60)=21 are poor
  probability of poor girl from total strength=21/100

• here,
  
  35% of (60%) are poor
  => (35/100)*(60/100)=21/100
  => probability is .21 out of 1.

• 60*35/10000=2700/10000=.21(21%)

• let there are 100 students
  therefore there 60 girls out of 100 students
  to find the probability of selecting a poor girl
  first of all we have to select a girl out of 100 students
  then we select a poor girl
  so the ans is:
  (60/100)(21/60)
  therefore probability is 21/100 or 21%

• let total no of students be 100
  then there are 60 girls and 40 boys
  35% of 60 means 3500/60 =350/6
  now probability of selecting a poor girl is (350/6)/100 = 35/60 = 7/12

• let we take total students are 100(boys &girls)
  60% are girls =100*(60/100)=60
  35% poor girls=60*(35/100)=21
  poor girl selected probability=21/100*(100)=21%

• let 100 be total strength
  60%=60
  probability of selecting a poor girl=((35%60)*100)%100=0.58

• let 100 girls are there...60% means 60 girls..and 35%of 60=(35/60)*100=21.
  so 21 girls out of 100..means 21100 is the probability.

• lets us assume total no of student in the class is 100
  then 60% of girls , it means 60 girils
  in that 35% poor, then 35/100*60=21
  probability 21/100.

• Total number of girls student is 60%
  poor girl students are 35%
  35/100 *60/100=21
  probability=no of poor girl student/total number of girl students
  =21/60
  =0.35
