If a family is chosen find the probability that the family is:


(i) earning Rs. 10,000 – 13,000 per month and owning exactly 2 vehicles.


(ii) earning Rs. 16,000 or more per month and owning exactly 1 vehicles.


(iii) earning less than Rs. 7,000 per month and does not own any vehicles.


(iv) earning Rs. 13,000 – 16,000 per month and owning more than 2 vehicles.


(v) owning not more than 1 vehicle.


(vi)owning at least one vehicle.

Given,


(i) The probability that the family is earning Rs. 10,000 – 13,000 per month and owning exactly 2 vehicles =


(ii) The probability that the family earning Rs. 16,000 or more per month and owning exactly 1 vehicles =


(iii) The probability that the family earning less than Rs. 7,000 per month and does not own any vehicles =


(iv) The probability that the family earning Rs. 13,000 – 16,000 per month and owning more than 2 vehicles =


(v) The probability that the family owning not more than 1 vehicle =


(vi) The probability that the family owning at least one vehicle =
