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:
$\begin{matrix} Monthly income(in Rs) & Vehicles per family 0 & 1 & 2 & A b o v e 2 Less than 7000 & 10 & 160 & 25 & 0 7000 - 10000 & 0 & 305 & 27 & 2 10000 - 13000 & 1 & 535 & 29 & 1 13000 - 16000 & 2 & 469 & 59 & 25 16000 or more & 1 & 579 & 82 & 88 \end{matrix}$
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.

Solution

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, $P = \frac{25}{2400} = \frac{1}{96}$
