In a class there are 60% of girls of which 25% poor. What is the probability that a poor girl is selected is leader?

• Assume total students in the class = 100
  Then Girls = 60% (100) = 60
  Poor girls = 25% (60) = 15
  So probability that a poor girls is selected leader = Poor girls / Total students = 15/100 = 15%

• total girls are=60%=60
  poor girls= 60*25/100=15
  probability the poor girl is selected as a leader=15/60=1/4

• No relation is given between poor girl and a leader.
  So it is not possible to find given probability.

• consider 100 students ....60% girls so 60 girls among them 25% poor so 25% of 60=15 so ans is 15/60=1/4
• 8 years agoHelpfull: Yes(2) No(5)
• 1-(40/100)-(45/100)=3/20
• 8 years agoHelpfull: Yes(2) No(0)
• Ans is 3/20
  (15 C 1) / (100 C 1)

• suppose there are 100 students are in the class
  60 are girls
  and 25% of 60 is 15
  so probability is 15/100=.15

• 15/60 as 25% of 60 is 15 & from total of 60 girls we have to select leader

• prob of girl sel is =60/100
  prob of girl is poor=25/60
  prob of poor girl sel=(0.6)*(5/12)=1/4

• as here we see that the total no of girls is 60.
  total no of poor girls=25/100*60=15

• Assume total students in the class = 100
  Then Girls = 60% (100) = 60
  Poor girls = 25% (60) = 15
  So probability that a poor girls is selected leader = Poor girls / Total students = 15/100 = 15%
