In a class there are 60% girls and out of them 45% are poor. A student is selected at random, find the probability that the student is a poor girl.

• ans:27/100
  let there be 100 students
  no of girls = 60
  45% of 60 are poor,poor girls=27
  probability=27/100

• Let us suppose the total strength of class be 100.
  The the number of girls will be 60 and hence the number of poor girls will be
  60*(45/100)=27
  So the probability of poor girl will be =27/100

• ans: 27
  
  prob=Possible events/total events
  possible = 45%(60%) ie 45/100(60/100)=27/100
  total=100
  divinding both we get 27 .!!

• answer is 0.27.
  probability of girl selected at random 0.6
  probability of poor girl among girls is 0.45
  therefore probability of poor girl=(0.6)*(0.45)=0.27

• @SAHITHI PRIYADARSHINI
  probability can't exceed "1"
  answer is 27/100 only..:)

• 18/100
  let total no of student 100 then total no of girls 60 and poor girls 45% of 60 girls i.e 18

• 18/100=0.18
