In a certain class room
Question : In a certain class , consisting of 60 boys and 40 girls, it is observed that 24 boys and 16 girls wear eyeglasses. What is the probability that a student picked at random wears eyeglasses , given that the student is a girl .

Solution :

What have you tried Zorro  this is an incredibly basic question.

Let A be the probabilty of wearing glasses and let B be the probabilty of being a girl
Now $\displaystyle P(A/B) = \frac{P(A\cap B)}{P(B)}$

My work 
Pr(E) :  Prob of eyeglases
Pr(G) :  prob of girl
$\displaystyle P(E/G) = \frac{Pr(E \cap G)}{P(G)} = \frac{\frac{16}{100}}{\frac{40}{100}} = \frac{16}{40}= \frac{2}{5}$.........Is this correct??????
