Question 5 (iv)
An organization selected 2400 families at random and surveyed them to determine a relationship between income level and the number of vehicles in a family. The information gathered is listed in the table below:

Suppose a family is chosen, find the probability that the family chosen is
(iv) earning Rs 13000-16000 per month and owning more than 2 vehicles.
Number of total families surveyed = 2400
(iv) Number of families earning Rs 13000−16000 per month and owning more than 2 vehicles =25
Hence, required probability, P=252400=196
