An Organisation selected 2400 families at random and surveyed them to determine a relationship between income level and the number of vehiclesin a family. The information gathered is listed in the table below :
Suppose a family is chosen. Find the probability that the family chosen is : not more than 1 vehicle.

An insurance company selected 2000 drivers at random (i.e., without any preference of one driver over another) in a particular city to find a relationship between age and accidents. The data obtained are given in the following table: Find the probabilities of the following events for a driver chosen at random from the city: having no accidents in one year.

An insurance company selected 2000 drivers at random (i.e., without any preference of one driver over another) in a particular city to find a relationship between age and accidents. The data obtained are given in the following table: Find the probabilities of the following events for a driver chosen at random from the city: being 30-50 years of age and having one or more accidents in a year.

An insurance company selected 2000 drivers at random (i.e., without any preference of one driver over another) in a particular city to find a relationship between age and accidents.
