Question

what is the empirical probability than an engineer lives​

Answer 1

• The distance (in km) of 40 engineers from their residence to their place of work were found as follows:
• 5 3 10 20 25 11 13 7 12 31 19 10 12 17 18 11 3 2 17 16 2 7 9 7 8 3 5 12 15 18 3 12 14 2 9 6 15 15 7 6 12

• Total number of engineers = 40

• (i) Number of engineers living less than 7 km from their place of work = 9

• Hence,

• Probability of engineers living less than 7 km from their place of work will be,

• (ii) Number of engineers living more than 7 km from their place of work = 40 – 9

• = 31

• Hence,

• Probability of engineers living more than 7 km from their place of work will be,

• (iii) Number of engineers living within � km from her place of work = 0

• Hence,

• Probability of engineers living within � km from her place of work would be,
