girls. Half of the girls wear glasses. A student is selected at random from the class. What is the probability that the student is a girl with glasses?
Answer by vcm(1) (Show Source): You can put this solution on YOUR website!
you have 16 total students. 8/16 of the class is girls. 4 out of the 8 girls wear glasses. So, in fraction form, you have 4/16, simplified to 1/4, of the students is a girl with glasses
as in rohit's 3/4 members wear glasses then the member's not wearing glasses
will be 1/4 as 1-3/4 =1/4.here 1 is the total no of members in rohit's family.
so,1/4 people in rohit's family dont wear glasses multiplied by Of those male who not wear glasses that is 1/3.so when you multiply the answer is 1/12 so 1/12 are the fraction of the family are males who do not wear glasses.
hope it helps
