Let's assume the number of students in the class be x.
Given that, Two-thirds of students in a class are girls.
So, number of girls 
Now ne-half of the girls wear glasses. So, one-half of
is
= 
=
Cancel out 2 from both numerator and denominator.
So, one third of the students are girls who wear glasses.
So, the correct choice is E.
Answer:


Step-by-step explanation:
An urn contains two blue balls (denoted
) and three white balls (denoted
).
In the selection, a ball is picked and replaced.
From the attached probability tree, the possible outcomes are:

(a)If the first ball drawn is blue
Number of Outcomes =10
The probability that the first ball drawn is blue 
(b)If only white balls are drawn
Number of Outcomes =9
Probability that only white balls are drawn
