What is the empirical probability that an engineer lives:
(i) less than 7 km from her place of work?
(ii)more than or equal to 7 km from her place of work?
(iii) within km from her place of work?
(i) Total number of engineers = 40
Number of engineers living less than 7 km from their place of work = 9
Hence, required probability that an engineer lives less than 7 km from her place of work,
(ii) Number of engineers living more than or equal to 7 km from their place of work = 40 − 9 = 31
Hence, required probability that an engineer lives more than or equal to 7 km from her place of work,
(iii) Number of engineers living within km from her place of work = 0
Hence, required probability that an engineer lives within km from her place of work, P = 0

Ans (i)
No. Of Engineer lives near less than 7 kms = 9
Probability for less than 7 km = 9/40
Ans (ii)
No. Of Engineer lives more than or equal to 7 kms = 40-9 = 31
Probability for more than or equal to 7 km = 31/40
Ans (iii)
No. Of engineer near 1/2 km = 0
Hence probability for 1/2 km is = 0/40 = 0
