Question 12 Marks
Given below is the frequency distribution table regarding the concentration of sulphur dioxide in the air in parts per million of a certain city for 30 days.
Find the probability of the concentration of sulphur dioxide in the interval 0.12 - 0.16 on any of these days.
| Concentration of SO2 | 0.00 - 0.04 | 0.04 - 0.08 | 0.08 - 0.12 | 0.12 - 0.16 | 0.16 - 0.20 | 0.20 - 0.24 |
| No. of days | 4 | 8 | 9 | 2 | 4 | 3 |

Probability of concentration of SO2 in interval 0.12 - 0.16
$=\frac{\text{Favorable out come}}{\text{Total out come}}$
$=\frac{2}{30}$
$=\frac{1}{15}$
$=0.06$
