A company selected 3000 households at random and surveyed them to find out a relationship between income level and the number of television sets in a home.

The information so obtained is listed in the following table

Find the probability

(i) of a household earning ₹(10000-14999) and have exactly one television.

(ii) of a household earning ₹ 25000 and more per month and owing 2 televisions.

(iii) of a household not having any television

∵Total number of households selected by the company = 3000

(i) The number of households earning

₹ (10000 -14999) per month and having exactly one television =240

(ii) The number of households earning ₹ 25000 and more per month and owing 2 televisions = 750

(iii) The number of households not having any television = 20 +10 = 30
