Q5. 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:
(v) owning not more than 1 vehicle.
Although it is given that,
Total no. of families= 2400
Let us find by this adding all the cases
= 10+0+1+2+1+160+305+535+469+579+25+27+29+59+82+0+2+1+25+88 =2400
Total number of families owning not more than 1 vehicle= 10+0+1+2+1+160+305+535+469+579 = 2062
Let, P(families owning not more than 1 vehicle)= P5
P5 = 2062/2400
