There are 100 students... and 40 boys.
What is the probability of getting a boy?
Student wears eye glasses. It looks like 40 wear eye glasses so 40/100 again.
I am not sure if the question is two separate problems or they are trying to say .. if you picked a boy and that he wears glasses? That would be a different approach.
