Given,
(i) The probability that the family is earning Rs. 10,000 – 13,000 per month and owning exactly 2 vehicles \(=\frac{favourable \,outcome}{total\,outcome}=\frac{29}{2400}\)
(ii) The probability that the family earning Rs. 16,000 or more per month and owning exactly 1 vehicles \(=\frac{favourable \,outcome}{total\,outcome}=\frac{579}{2400}\)
(iii) The probability that the family earning less than Rs. 7,000 per month and does not own any vehicles \(=\frac{favourable \,outcome}{total\,outcome}=\frac{10}{2400}=\frac{1}{240}\)
(iv) The probability that the family earning Rs. 13,000 – 16,000 per month and owning more than 2 vehicles \(=\frac{favourable \,outcome}{total\,outcome}=\frac{25}{2400}=\frac{1}{96}\)
(v) The probability that the family owning not more than 1 vehicle \(=\frac{favourable \,outcome}{total\,outcome}=\frac{10+0+1+2+1+160+305+535+469+579}{2400}\)
\(=\frac{2062}{2400}=\frac{1031}{1200}\)
(vi) The probability that the family owning at least one vehicle \(=\frac{favourable \,outcome}{total\,outcome}\)
\(=\frac{160+305+535+469+579+254+27+29+29+82+0+2+1+25+86}{2400}\)
\(=\frac{2356}{2400}=\frac{589}{600}\)
