57. 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? [SASTRA, JNTUK]

• Let take 100 students
  outoff 100 60 are girls
  among girls poor girls are =35% 0f 60=21
  pbt of selecting poor girl in total strength=21/100

• consider there are 100 menbers in school then in that 60% are girls means 60 mem girls are tthere
  then 35% are poor in that 60 mem so 35% of 60=35/100*60=21
  the probability is=21/100

• Let total num of student in a school are 100
  den num of girls=60
  and 35% of 60=21
  so probablity of selecting poor girl out of total strenth will b 21/100.

• assume there are 100 students and out of them 60 are girls
  35% of girls are poor = 35% of 60 = 21
  thus the probability of selecting a poor girl out of total strength= 21/100
  so ans = 21/100

• 35% of 60=21
  Probability of selecting a poor girl=21/60

• Take the sample is 100.
  That 60% were girls.
  out of 100%, 35% of the girls are poor
  The probability of selecting a poor girl in total is = 35/100

• 21/100
  Let 35% of 60% of 100 =21
  so 21/100
• 8 years agoHelpfull: Yes(0) No(0)
• Assume there are a total of 100 students out of which 60% are girls , so no: of girls =60
  and 35% of 60 is 21.
  so the probability of selecting poor girl is 21/100
  =0.21

• Poor girls 35percerntage
  Total 35×60/100=21/100
