Question

Refer to Q.2, Exercise 14.2. What is the empirical probability that an engineer lives:
(1) less than 7 km from her place of work?
(2) more than or equal to 7 km from her place of work? (3) within 1 upon 2
km from her place of work?
​

Answer 1

Answer:

Total number of engineers = 40

Also, Number of engineers living in less than 7 km from their place of work = 9

Hence, required probability that an engineer lives less than 7 km from her place =

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)Hence, required probability that an engineer lives within km from her place of work is P = 0.
