In a classroom of 30 students, 12 are boys and the rest are girls. If 8 boys wear glasses and 6 girls wear glasses, what is the probability that a randomly chosen student wears glasses?
The probability that a randomly chosen student wears glasses is 14/30 or 7/15.

Here's the reasoning:

1. We know that there are 12 boys and 18 girls in the classroom (since there are 30 students in total).
2. Out of these students, 8 boys and 6 girls wear glasses, which means a total of 8 + 6 = 14 students wear glasses.
3. To find the probability that a randomly chosen student wears glasses, we divide the number of students who wear glasses by the total number of students: 14/30.
4. Simplifying this fraction gives us 7/15.

So, the probability that a randomly chosen student wears glasses is 7/15.
