Answer:
(1) 61/2000
(2) 9/80
(3) 261/400
Step-by-step explanation:
Probability = number of favorable outcomes / total possibilities
(1) Given :
Number of drivers in total :
= 2000
Possibilities = 2000
Now, drivers having 3 accidents = 61 [ of age 18 - 29 ]
Favourable outcomes = 61
Probability = 61/2000
=========================================================
(2) Number of drivers in total:
= 2000
Possibilities = 2000
Drivers having one or more accidents ( 30 - 50 years )
= 125 + 60 + 22 + 18
= 125 + 100
= 225
Favorable outcomes = 225
Probability = 225/2000
= 45/400
= 9/80
=========================================================
(3) Given :
Number of drivers in total :
= 2000
Possibilities = 2000
Number of drivers with no accidents at all :
= 360 + 440 + 505
= 1305
Probability = 1305/2000
= 261/400
=========================================================
