Read Solution (Total 3)
-
- 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 - 10 years agoHelpfull: Yes(4) No(0)
- ans: 21/100
soln:
60/100=60
35% of 60=21
hence selecting poor girl from 100 students is 21/100 - 10 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 - 10 years agoHelpfull: Yes(1) No(0)
