The table shows the ages of students in a class. What is the probability that a student chosen at random is less than 18 years old?
| Age (years) |
16 |
17 |
18 |
| No. of students |
4 |
8 |
6 |
Worked solution (try it first)
There are
4+8+6=18 students.
Less than 18 years means 16 or 17:
4+8=12 students.
So the probability is
1812=32, option C.
