in a school there are 60% girls.35 % of them are poor.what is the probability that apoor girl is selected as shool head?

• 60*35/100=21/100=0.21
• 9 years agoHelpfull: Yes(17) No(0)
• probability of selecting a girl= 60/100 = 0.6
  probability of selecting a poor girl = 35/100= 0.35
  therefore, probability that poor girl is selected as school head = 0.6*0.35= 0.21

• Let total no of students be x
  60% of x=.6x
  poor girls=35% of .6x
  probability= (35% * .6x)/x = 21/100 ans

• If suppose 100 students in a school 60 are girls,35% means 21 are poor
  therefore selecting poor girl is21c1=21
  total 60 girls
  so 21/60
  am i crct or nt

• let assume there are 100 student in the class and out of which 60 are girls and out of 60 (let it 100 percent ) 35 percent are poor then (60/100)*35 = 21 then the probability is 21/100

• let the total student is x
  then {(x)(60/100)(35/100)}/x=.21
• 9 years agoHelpfull: Yes(1) No(0)
• there is a girl=60%
  now no. of poor girl=(60/100)*(35/100)=21/100
  hence required ans is 0.21

• 0.6*0.35=0.21
• 9 years agoHelpfull: Yes(0) No(1)
• (60*35)/(100/100)=0.21
  because first we have to select girl and then poor.
  probability of selecting a girl=60/100
  probability of selecting a poor girl=probability of selecting a girl*35/100

• probability of selecting a girl=60/100
  probability of selecting a poor girl=60/100*(35/100*60/100)=63/500

• let us take total 100 out of which 60 are girls and among 60,35 are poor..so,35/60=7/12
• 9 years agoHelpfull: Yes(0) No(2)
• suppose there are 100 students
  60 students are girls out of 100
  35% of girls are poor mean 21 are poor
  probability= 21/100 =0.21
• 9 years agoHelpfull: Yes(0) No(0)
• let no of students=100
  girls=60% of 100=60
  poor girls=35% of 60=21
  required probability=21/60
