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

• lets total no of students be 100
  no of girls = 60%of 100=60
  no of girls poor= 35%of 60=21
  probability of selecting poor girls =21/100

• ans: 21/100
  soln:
  60/100=60
  35% of 60=21
  hence selecting poor girl from 100 students is 21/100
• 9 years agoHelpfull: Yes(1) No(0)
• let there are 100 students
  so no of girl= 60
  no of poor girl= 60*35%=21
  then probability P(E)=21/100
