Answer :

Total number of families = 2400

(i) Number of families earning Rs. 10,000 – 13,000 per month and owning exactly two vehicles = 29

Hence,

Probability of families earning Rs. 10,000 – 13,000 per month and owning exactly two vehicles will be,

(ii) Number of families earning Rs. 16000 or more per month and owning exactly one vehicle = 579

Hence,

Probability of families earning Rs. 16000 or more per month and owning exactly one vehicle will be,

(iii) Number of families earning less than Rs. 7000 per month and does not own any vehicle = 10

Hence,

Probability of families earning less than Rs. 7,000 per month and doesn’t own any vehicles will be,

(iv) Number of families earning Rs. 13,000-16000 per month and owning more than two vehicles = 25

Hence,

Probability of families earning Rs. 13,000-16000 per month and owning more than two vehicles will be,

(v) Number of families owning not more than 1 vehicle are

= 10 + 160 + 0 + 305 + 1 + 535 + 2 + 469 + 1 + 579

= 2062

Hence,

Probability of families owning not more than one vehicle will be
