An insurance company selected 6000 drivers from a city at random in order to find a relationship between age and accidents. The following table shows the results to these 6000 drivers.
| Age of drivers (in years) Class Interval | Accidents in one year | ||||
| 0 | 1 | 2 | 3 | 4 or more | |
| 18 – 25 | 700 | 310 | 225 | 110 | 85 |
| 25 – 40 | 1100 | 290 | 200 | 105 | 80 |
| 40 – 50 | 1200 | 235 | 175 | 80 | 55 |
| 50 and above | 600 | 205 | 140 | 70 | 35 |
If a driver from the city is selected at random, find the probability of the following events:
a) Age lying between 18 – 25 and meet 3 accidents
b) Age lying between 18 – 40 and meet 1 accident
c) Age more than 25 years and meet at most one accident
d) Having no accident in the year
e) Age lying between 18 – 40 and meet at least 3 accidents
Since the information is based on 6000 drivers,
the number of exhaustive cases is = 6000.
Thus,
The required probabilities are -
a) Probability that the ________ ___ _______ __________ ________ _______ _____ _________ ________ ____ __________.
