A company selected 2400 families at random and survey them to determine a relationship between income level and the number of vehicles in a home. The information gathered is listed in the table below:   Monthly income (in Rs.)       Vehicles per family                                       0                 1                                      2                                      Above 2 Less than 7000 7000-10000 10000-13000 13000-16000 16000 or more 10 0 1 2 1          160 305 535 469 579      25 27 29 29 82        0 2 1 25 88 If a family is chosen, find the probability that the family is: (i)               earning Rs. 10000-13000 per month and owning exactly 2 vehicles.
