Given below is the frequency distribution table regarding the concentration of SO2 in the air in parts per million of a certain city for 30 days.
Find the probability of the concentration of SO2 in the interval 0.12-0.16 on any of these days.
Solution:
Total no of days: 30
Probability of concentration of SO2 in interval 0.12 - 0.16
$=\frac{\text { Favorable out come }}{\text { Total out come }}$
= 2/30
= 1/15
= 0.06
