A study was conducted to find out the concentration of sulphur dioxide in the air in parts per million (ppm) of a certain city. The data obtained for 30 days is as follows : You were asked to prepare a frequency distribution table, regarding the concentration of sulphur dioxide in the air in parts per million (ppm) of a certain city for 30 days . Using this table, find the probability of the concentration of sulphur dioxide in the interval 0.12-0.16 on any of these days.
