Question 972806: In a class of 60 boys and 40 girls, it is observed that 24 boys and 21 girls wear glasses. What is the probability that:
1. A student picked at random from this class wears glasses
1. There are 60 plus 40 = 100 students and 24 plus 21 = 45 of them wear glasses. If A is the event that a selected student wears glasses, then P(A) = the number of students that wear glasses divided by the number of students. You can do your own arithmetic.
